Kudosâ„¢ plants are more compact and tidier, with dense, long-flowering blooms that retain their colorful calyxes even after the flowers fade. Physical Characteristics Agastache plants typically grow between 1 and 3 feet tall, with a similar spread. However, some species can reach up to 6 feet in height. They have an upright, clump-forming habit with sturdy square stems characteristic of the mint family. The leaves are generally lance-shaped with toothed edges and come in various shades of green, gray-green, or gold. When crushed, the leaves release a fragrant aroma, often reminiscent of anise or licorice. For instance, A. rupestris has a unique "root beer" scent. The flowers of Agastache are arranged in dense, terminal spikes, creating a striking display. They come in a wide array of colors, including blue, purple, pink, orange, and white. The individual flowers are tubular and two-lipped, typical of the mint family. Native Habitat Agastache species are predominantly found in dry and often hilly areas of North America, China, and Japan. They thrive in full sun and well-drained soil. Varieties from Mexico and the Southwest US require excellent drainage. Agastache foeniculum, or anise hyssop, is native to prairies, dry upland forested areas, plains, and fields in the upper Midwest and Great Plains of North America. It prefers full sun to partial shade and tolerates a wide range of soils as long as they are well-drained. It is hardy to zones 3-8. Agastache rugosa, or Korean mint, is native to moist grasslands, valleys, and stream banks in China, Vietnam, Laos, Korea, and Japan. Unlike the more drought-tolerant native species, A. rugosa and its hybrids are better suited to the more humid climates of the eastern US. Landscaping Design Tips Agastache's versatility, long blooming period, and ability to grow in both the ground and containers allow for greater flexibility in garden design. It is an excellent choice for various garden designs: Perennial Borders: Agastache adds height and color to perennial borders, especially in mid-to-late summer when many other plants are fading. Its upright habit provides structure and visual interest, while its vibrant flower spikes create focal points within the border. Butterfly Gardens: The nectar-rich flowers of Agastache are a magnet for butterflies, making it an essential component of any butterfly garden. Combine it with other butterfly-friendly plants like Buddleja (butterfly bush), Asclepias (milkweed), and Echinacea (coneflower) to create a haven for these beautiful pollinators. Cottage Gardens: Agastache's informal growth habit and vibrant colors blend seamlessly into cottage gardens. Its long blooming season ensures continuous color throughout the summer and fall, complementing the relaxed and abundant style of cottage gardens. Herb Gardens: Some Agastache species, such as anise hyssop (Agastache foeniculum), have culinary and medicinal uses, making them suitable for herb gardens. The leaves can be used to make tea or add flavor to salads and other dishes. Xeriscapes: Agastache's drought tolerance makes it a valuable addition to xeriscapes or dry gardens. Combine it with other drought-tolerant plants like Lavandula (lavender), Salvia (sage), and Perovskia (Russian sage) to create a water-wise landscape that requires minimal irrigation. Containers: Agastache can be grown in containers, provided they are placed in a sunny location and have adequate drainage. Choose compact varieties for smaller containers and taller varieties for larger pots. When designing with Agastache, consider the following: Color Palette: Agastache flowers come in a wide range of colors, allowing you to create vibrant displays by pairing them with plants that have complementary or contrasting colors. Companion Plants: Agastache combines well with various perennials, including Echinacea (coneflower), Rudbeckia hirta (black-eyed Susan), Sedum (stonecrop), Salvia (sage), Lavandula angustifolia (English lavender), and Crocosmia (Montbretia). Height and Spread: Choose Agastache varieties that fit the scale of your garden, considering their mature height and spread. Planting and Care Agastache is relatively easy to grow and care for, requiring minimal maintenance once established. Here are some essential guidelines: Planting Timing: Plant Agastache in spring after the danger of frost has passed. Location: Choose a sunny site with well-drained soil. Soil Preparation: Loosen the soil and amend it with compost to improve drainage and fertility. Spacing: Space plants 12 to 15 inches apart.

Agastache’s Critter, Pest and Disease Resistance Agastache is generally considered a low-maintenance plant that does not attract many pests or diseases. Here is a breakdown of their resistance: Critter Resistance: Deer resistant: Deer tend to leave Agastache alone due to the foliage's somewhat coarse texture and mild anise scent. Rabbit resistant: Rabbits are not particularly attracted to Agastache and will usually leave them be. Pest Resistance: Agastache is relatively pest-resistant, but a few minor pests can occasionally trouble them: Aphids: These tiny, sap-sucking insects can sometimes infest the stems and leaves. You can control them with insecticidal soap or neem oil spray. Spittlebugs: These create foamy masses around themselves on the plant. A strong jet of water can dislodge them, or insecticidal soap can be used for larger infestations. Disease Resistance: Agastache is generally disease-resistant, but there are a couple of potential issues to watch for: Powdery mildew: This fungal disease can cause white powdery spots on the leaves. Improve air circulation by thinning overcrowded plants and avoid overhead watering. In severe cases, a fungicide may be necessary. Root rot: This can occur in poorly drained soils. Ensure the soil drains well and water only when needed. By providing proper care, including well-drained soil, adequate sunlight, and avoiding overwatering, you can help your Agastache thrive and resist pests and diseases. Planting Bare Root Agastache Timing: The best time to plant bare root Agastache depends on your climate zone: Fall planting: Ideally suited for zones 5-7. Plant bare root Agastache in fall, at least 4-6 weeks before the ground freezes. This allows the roots to establish before winter. Early spring planting: For zones 8-10, or if you miss the fall planting window, early spring (as soon as the ground thaws and can be worked) is acceptable. Before Planting: Inspect the bare root Agastache. The roots should be plump and white, not mushy or shriveled. If planting is not happening right away, store the bare root Agastache in a cool, moist place (like a refrigerator) for a short period. Planting: Choose a planting location that receives full sun and has well-drained soil. Agastache will not tolerate soggy conditions. Dig a hole that is twice the width of the root spread of the Agastache. If your soil is heavy clay, amend the planting hole with compost or other organic matter to improve drainage. Gently loosen and spread out the roots of the Agastache plant. Position the plant in the hole so that the crown (the point where the roots and stems meet) sits at soil level. Backfill the hole with soil, tamping it down gently to remove air pockets. Water the plant thoroughly to settle the soil around the roots. After Planting: Water your newly planted Agastache regularly, especially during dry periods, until it is established (usually after a few weeks). Apply a layer of mulch around the base of the plant to help retain moisture and suppress weeds. Avoid overfertilizing, as Agastache generally does not require much additional fertilizer. With proper care, your bare root Agastache should establish itself quickly and reward you with beautiful blooms throughout the summer. × OK

Agastache’s Critter, Pest and Disease Resistance Agastache is generally considered a low-maintenance plant that does not attract many pests or diseases. Here is a breakdown of their resistance: Critter Resistance: Deer resistant: Deer tend to leave Agastache alone due to the foliage's somewhat coarse texture and mild anise scent. Rabbit resistant: Rabbits are not particularly attracted to Agastache and will usually leave them be. Pest Resistance: Agastache is relatively pest-resistant, but a few minor pests can occasionally trouble them: Aphids: These tiny, sap-sucking insects can sometimes infest the stems and leaves. You can control them with insecticidal soap or neem oil spray. Spittlebugs: These create foamy masses around themselves on the plant. A strong jet of water can dislodge them, or insecticidal soap can be used for larger infestations. Disease Resistance: Agastache is generally disease-resistant, but there are a couple of potential issues to watch for: Powdery mildew: This fungal disease can cause white powdery spots on the leaves. Improve air circulation by thinning overcrowded plants and avoid overhead watering. In severe cases, a fungicide may be necessary. Root rot: This can occur in poorly drained soils. Ensure the soil drains well and water only when needed. By providing proper care, including well-drained soil, adequate sunlight, and avoiding overwatering, you can help your Agastache thrive and resist pests and diseases. Planting Bare Root Agastache Timing: The best time to plant bare root Agastache depends on your climate zone: Fall planting: Ideally suited for zones 5-7. Plant bare root Agastache in fall, at least 4-6 weeks before the ground freezes. This allows the roots to establish before winter. Early spring planting: For zones 8-10, or if you miss the fall planting window, early spring (as soon as the ground thaws and can be worked) is acceptable. Before Planting: Inspect the bare root Agastache. The roots should be plump and white, not mushy or shriveled. If planting is not happening right away, store the bare root Agastache in a cool, moist place (like a refrigerator) for a short period. Planting: Choose a planting location that receives full sun and has well-drained soil. Agastache will not tolerate soggy conditions. Dig a hole that is twice the width of the root spread of the Agastache. If your soil is heavy clay, amend the planting hole with compost or other organic matter to improve drainage. Gently loosen and spread out the roots of the Agastache plant. Position the plant in the hole so that the crown (the point where the roots and stems meet) sits at soil level. Backfill the hole with soil, tamping it down gently to remove air pockets. Water the plant thoroughly to settle the soil around the roots. After Planting: Water your newly planted Agastache regularly, especially during dry periods, until it is established (usually after a few weeks). Apply a layer of mulch around the base of the plant to help retain moisture and suppress weeds. Avoid overfertilizing, as Agastache generally does not require much additional fertilizer. With proper care, your bare root Agastache should establish itself quickly and reward you with beautiful blooms throughout the summer. × OK

Renowned for its aromatic leaves and long-lasting, colorful flower spikes that persist throughout the summer and into fall, sometimes even until frost, Agastache offers a multitude of benefits for both novice and experienced gardeners. This comprehensive guide will delve into the unique features of Agastache, explore its various aspects, and provide valuable insights into its native habitat, landscaping design tips, and essential planting and care instructions. What is Agastache? Agastache is a genus of aromatic flowering plants belonging to the mint family (Lamiaceae). Most Agastache species are native to North America, with a significant concentration in the southwestern United States and northern Mexico. These plants are renowned for their long-lasting flower spikes and ability to tolerate heat and early frosts. Some species, like A. foeniculum (Anise hyssop), are also used in herbal medicines and teas. Common Names and Varieties Agastache is known by several common names, each highlighting a different characteristic of the plant: Common Name Description Varieties Hummingbird Mint This name emphasizes the plant's popularity with hummingbirds, which are drawn to its nectar-rich flowers.

Kudosâ„¢ plants are more compact and tidier, with dense, long-flowering blooms that retain their colorful calyxes even after the flowers fade. Physical Characteristics Agastache plants typically grow between 1 and 3 feet tall, with a similar spread. However, some species can reach up to 6 feet in height. They have an upright, clump-forming habit with sturdy square stems characteristic of the mint family. The leaves are generally lance-shaped with toothed edges and come in various shades of green, gray-green, or gold. When crushed, the leaves release a fragrant aroma, often reminiscent of anise or licorice. For instance, A. rupestris has a unique "root beer" scent. The flowers of Agastache are arranged in dense, terminal spikes, creating a striking display. They come in a wide array of colors, including blue, purple, pink, orange, and white. The individual flowers are tubular and two-lipped, typical of the mint family.

Renowned for its aromatic leaves and long-lasting, colorful flower spikes that persist throughout the summer and into fall, sometimes even until frost, Agastache offers a multitude of benefits for both novice and experienced gardeners. This comprehensive guide will delve into the unique features of Agastache, explore its various aspects, and provide valuable insights into its native habitat, landscaping design tips, and essential planting and care instructions. What is Agastache? Agastache is a genus of aromatic flowering plants belonging to the mint family (Lamiaceae). Most Agastache species are native to North America, with a significant concentration in the southwestern United States and northern Mexico. These plants are renowned for their long-lasting flower spikes and ability to tolerate heat and early frosts. Some species, like A. foeniculum (Anise hyssop), are also used in herbal medicines and teas. Common Names and Varieties Agastache is known by several common names, each highlighting a different characteristic of the plant: Common Name Description Varieties Hummingbird Mint This name emphasizes the plant's popularity with hummingbirds, which are drawn to its nectar-rich flowers. 'Firebird', 'Raspberry Summer', 'Kudos Ambrosia' Anise Hyssop This name refers to the anise scent of some varieties, similar to hyssop. Agastache foeniculum, 'Blue Fortune', 'Black Adder' Giant Hyssop This name points to their resemblance to hyssop but with a larger size. 'Blue Boa', 'Blue Fortune' Fragrant Giant Hyssop This name combines the size and pleasant fragrance of the plant. 'Summer Glow', 'Bolero' Lavender Giant Hyssop This name is specific to varieties with lavender-colored flowers. 'Blue Fortune', 'Little Adder' There are about 30 species of Agastache, with four commonly found in gardens: Agastache foeniculum, Agastache mexicana, Agastache rugosa, and Agastache rupestris. Some popular varieties include: 'Blue Fortune': This hybrid variety features lavender-blue flowers and is known for its hardiness and long bloom time. 'Black Adder': This variety has violet-red flowers and a compact growth habit. 'Firebird': With its coral orange flowers, this variety is a favorite of hummingbirds. 'Golden Jubilee': This variety stands out with its chartreuse-colored foliage. 'Summer Breeze': This variety boasts a long bloom time and a delightful fragrance. 'Blue Boa': Characterized by large, deep purple-blue flowers, a long bloom time, a stiffly upright habit, and excellent vigor. This cultivar is a selection from a breeding line using Agastache rugosa as a parent to provide cold hardiness and wet soil tolerance. In addition to these, the Kudosâ„¢ Agastache series deserves special mention. This series was specifically bred for increased tolerance to moisture and cold, expanding the potential growing range of Agastache and making it suitable for more diverse climates. These hybrids combine the traits of Southwestern US and Mexican species, which tolerate heat and drought, with Agastache rugosa, an Asian species that better tolerates moisture and colder winters. Kudosâ„¢ plants are more compact and tidier, with dense, long-flowering blooms that retain their colorful calyxes even after the flowers fade. Physical Characteristics Agastache plants typically grow between 1 and 3 feet tall, with a similar spread. However, some species can reach up to 6 feet in height. They have an upright, clump-forming habit with sturdy square stems characteristic of the mint family. The leaves are generally lance-shaped with toothed edges and come in various shades of green, gray-green, or gold. When crushed, the leaves release a fragrant aroma, often reminiscent of anise or licorice. For instance, A. rupestris has a unique "root beer" scent. The flowers of Agastache are arranged in dense, terminal spikes, creating a striking display. They come in a wide array of colors, including blue, purple, pink, orange, and white. The individual flowers are tubular and two-lipped, typical of the mint family. Native Habitat Agastache species are predominantly found in dry and often hilly areas of North America, China, and Japan. They thrive in full sun and well-drained soil. Varieties from Mexico and the Southwest US require excellent drainage. Agastache foeniculum, or anise hyssop, is native to prairies, dry upland forested areas, plains, and fields in the upper Midwest and Great Plains of North America. It prefers full sun to partial shade and tolerates a wide range of soils as long as they are well-drained. It is hardy to zones 3-8. Agastache rugosa, or Korean mint, is native to moist grasslands, valleys, and stream banks in China, Vietnam, Laos, Korea, and Japan. Unlike the more drought-tolerant native species, A. rugosa and its hybrids are better suited to the more humid climates of the eastern US. Landscaping Design Tips Agastache's versatility, long blooming period, and ability to grow in both the ground and containers allow for greater flexibility in garden design. It is an excellent choice for various garden designs: Perennial Borders: Agastache adds height and color to perennial borders, especially in mid-to-late summer when many other plants are fading. Its upright habit provides structure and visual interest, while its vibrant flower spikes create focal points within the border. Butterfly Gardens: The nectar-rich flowers of Agastache are a magnet for butterflies, making it an essential component of any butterfly garden. Combine it with other butterfly-friendly plants like Buddleja (butterfly bush), Asclepias (milkweed), and Echinacea (coneflower) to create a haven for these beautiful pollinators. Cottage Gardens: Agastache's informal growth habit and vibrant colors blend seamlessly into cottage gardens. Its long blooming season ensures continuous color throughout the summer and fall, complementing the relaxed and abundant style of cottage gardens. Herb Gardens: Some Agastache species, such as anise hyssop (Agastache foeniculum), have culinary and medicinal uses, making them suitable for herb gardens. The leaves can be used to make tea or add flavor to salads and other dishes. Xeriscapes: Agastache's drought tolerance makes it a valuable addition to xeriscapes or dry gardens. Combine it with other drought-tolerant plants like Lavandula (lavender), Salvia (sage), and Perovskia (Russian sage) to create a water-wise landscape that requires minimal irrigation. Containers: Agastache can be grown in containers, provided they are placed in a sunny location and have adequate drainage. Choose compact varieties for smaller containers and taller varieties for larger pots. When designing with Agastache, consider the following: Color Palette: Agastache flowers come in a wide range of colors, allowing you to create vibrant displays by pairing them with plants that have complementary or contrasting colors. Companion Plants: Agastache combines well with various perennials, including Echinacea (coneflower), Rudbeckia hirta (black-eyed Susan), Sedum (stonecrop), Salvia (sage), Lavandula angustifolia (English lavender), and Crocosmia (Montbretia). Height and Spread: Choose Agastache varieties that fit the scale of your garden, considering their mature height and spread. Planting and Care Agastache is relatively easy to grow and care for, requiring minimal maintenance once established. Here are some essential guidelines: Planting Timing: Plant Agastache in spring after the danger of frost has passed. Location: Choose a sunny site with well-drained soil. Soil Preparation: Loosen the soil and amend it with compost to improve drainage and fertility. Spacing: Space plants 12 to 15 inches apart. Self-Sowing: Agastache readily self-sows, especially in colder climates. If you want to prevent this, deadhead the flowers before they go to seed. Care Watering: Water regularly until plants are established, then water occasionally as needed. Agastache is drought-tolerant once established. Fertilizing: Agastache prefers lean soil and typically does not require fertilizer. Over-fertilization can negatively impact the plant's growth and flowering, causing it to produce fewer blooms and become floppy. Mulching: Mulching is generally not necessary, but a thin layer of pine needles or crushed stone can help retain moisture and suppress weeds. Pruning: Deadhead spent flowers to encourage rebloom. In late winter or early spring, cut back the remaining stems to the ground. Dividing: Divide plants every 3 to 5 years to rejuvenate them. Propagation Agastache can be propagated from seed or cuttings. Seed Propagation: Sow seeds in early spring when the soil temperature is between 55-64°F. Start seeds indoors 4-6 weeks before the last frost or sow directly into the garden after the last frost. Cuttings: Take semi-ripe cuttings in summer. Dip the cut ends in rooting hormone and plant them in a moist potting mix. Keep the cuttings in a warm, humid environment until they root.

Butterfly Gardens: The nectar-rich flowers of Agastache are a magnet for butterflies, making it an essential component of any butterfly garden. Combine it with other butterfly-friendly plants like Buddleja (butterfly bush), Asclepias (milkweed), and Echinacea (coneflower) to create a haven for these beautiful pollinators. Cottage Gardens: Agastache's informal growth habit and vibrant colors blend seamlessly into cottage gardens. Its long blooming season ensures continuous color throughout the summer and fall, complementing the relaxed and abundant style of cottage gardens. Herb Gardens: Some Agastache species, such as anise hyssop (Agastache foeniculum), have culinary and medicinal uses, making them suitable for herb gardens. The leaves can be used to make tea or add flavor to salads and other dishes. Xeriscapes: Agastache's drought tolerance makes it a valuable addition to xeriscapes or dry gardens. Combine it with other drought-tolerant plants like Lavandula (lavender), Salvia (sage), and Perovskia (Russian sage) to create a water-wise landscape that requires minimal irrigation. Containers: Agastache can be grown in containers, provided they are placed in a sunny location and have adequate drainage. Choose compact varieties for smaller containers and taller varieties for larger pots. When designing with Agastache, consider the following: Color Palette: Agastache flowers come in a wide range of colors, allowing you to create vibrant displays by pairing them with plants that have complementary or contrasting colors. Companion Plants: Agastache combines well with various perennials, including Echinacea (coneflower), Rudbeckia hirta (black-eyed Susan), Sedum (stonecrop), Salvia (sage), Lavandula angustifolia (English lavender), and Crocosmia (Montbretia). Height and Spread: Choose Agastache varieties that fit the scale of your garden, considering their mature height and spread. Planting and Care Agastache is relatively easy to grow and care for, requiring minimal maintenance once established. Here are some essential guidelines: Planting Timing: Plant Agastache in spring after the danger of frost has passed. Location: Choose a sunny site with well-drained soil. Soil Preparation: Loosen the soil and amend it with compost to improve drainage and fertility. Spacing: Space plants 12 to 15 inches apart.

Agastache’s Critter, Pest and Disease Resistance Agastache is generally considered a low-maintenance plant that does not attract many pests or diseases. Here is a breakdown of their resistance: Critter Resistance: Deer resistant: Deer tend to leave Agastache alone due to the foliage's somewhat coarse texture and mild anise scent. Rabbit resistant: Rabbits are not particularly attracted to Agastache and will usually leave them be. Pest Resistance: Agastache is relatively pest-resistant, but a few minor pests can occasionally trouble them: Aphids: These tiny, sap-sucking insects can sometimes infest the stems and leaves. You can control them with insecticidal soap or neem oil spray. Spittlebugs: These create foamy masses around themselves on the plant. A strong jet of water can dislodge them, or insecticidal soap can be used for larger infestations. Disease Resistance: Agastache is generally disease-resistant, but there are a couple of potential issues to watch for: Powdery mildew: This fungal disease can cause white powdery spots on the leaves. Improve air circulation by thinning overcrowded plants and avoid overhead watering. In severe cases, a fungicide may be necessary. Root rot: This can occur in poorly drained soils. Ensure the soil drains well and water only when needed. By providing proper care, including well-drained soil, adequate sunlight, and avoiding overwatering, you can help your Agastache thrive and resist pests and diseases. Planting Bare Root Agastache Timing: The best time to plant bare root Agastache depends on your climate zone: Fall planting: Ideally suited for zones 5-7. Plant bare root Agastache in fall, at least 4-6 weeks before the ground freezes. This allows the roots to establish before winter. Early spring planting: For zones 8-10, or if you miss the fall planting window, early spring (as soon as the ground thaws and can be worked) is acceptable. Before Planting: Inspect the bare root Agastache. The roots should be plump and white, not mushy or shriveled. If planting is not happening right away, store the bare root Agastache in a cool, moist place (like a refrigerator) for a short period. Planting: Choose a planting location that receives full sun and has well-drained soil. Agastache will not tolerate soggy conditions. Dig a hole that is twice the width of the root spread of the Agastache. If your soil is heavy clay, amend the planting hole with compost or other organic matter to improve drainage. Gently loosen and spread out the roots of the Agastache plant. Position the plant in the hole so that the crown (the point where the roots and stems meet) sits at soil level. Backfill the hole with soil, tamping it down gently to remove air pockets. Water the plant thoroughly to settle the soil around the roots. After Planting: Water your newly planted Agastache regularly, especially during dry periods, until it is established (usually after a few weeks). Apply a layer of mulch around the base of the plant to help retain moisture and suppress weeds. Avoid overfertilizing, as Agastache generally does not require much additional fertilizer. With proper care, your bare root Agastache should establish itself quickly and reward you with beautiful blooms throughout the summer. × OK

Agastache’s Critter, Pest and Disease Resistance Agastache is generally considered a low-maintenance plant that does not attract many pests or diseases. Here is a breakdown of their resistance: Critter Resistance: Deer resistant: Deer tend to leave Agastache alone due to the foliage's somewhat coarse texture and mild anise scent. Rabbit resistant: Rabbits are not particularly attracted to Agastache and will usually leave them be. Pest Resistance: Agastache is relatively pest-resistant, but a few minor pests can occasionally trouble them: Aphids: These tiny, sap-sucking insects can sometimes infest the stems and leaves. You can control them with insecticidal soap or neem oil spray. Spittlebugs: These create foamy masses around themselves on the plant. A strong jet of water can dislodge them, or insecticidal soap can be used for larger infestations. Disease Resistance: Agastache is generally disease-resistant, but there are a couple of potential issues to watch for: Powdery mildew: This fungal disease can cause white powdery spots on the leaves. Improve air circulation by thinning overcrowded plants and avoid overhead watering. In severe cases, a fungicide may be necessary. Root rot: This can occur in poorly drained soils. Ensure the soil drains well and water only when needed. By providing proper care, including well-drained soil, adequate sunlight, and avoiding overwatering, you can help your Agastache thrive and resist pests and diseases. Planting Bare Root Agastache Timing: The best time to plant bare root Agastache depends on your climate zone: Fall planting: Ideally suited for zones 5-7. Plant bare root Agastache in fall, at least 4-6 weeks before the ground freezes. This allows the roots to establish before winter. Early spring planting: For zones 8-10, or if you miss the fall planting window, early spring (as soon as the ground thaws and can be worked) is acceptable. Before Planting: Inspect the bare root Agastache. The roots should be plump and white, not mushy or shriveled. If planting is not happening right away, store the bare root Agastache in a cool, moist place (like a refrigerator) for a short period. Planting: Choose a planting location that receives full sun and has well-drained soil. Agastache will not tolerate soggy conditions. Dig a hole that is twice the width of the root spread of the Agastache. If your soil is heavy clay, amend the planting hole with compost or other organic matter to improve drainage. Gently loosen and spread out the roots of the Agastache plant. Position the plant in the hole so that the crown (the point where the roots and stems meet) sits at soil level. Backfill the hole with soil, tamping it down gently to remove air pockets. Water the plant thoroughly to settle the soil around the roots. After Planting: Water your newly planted Agastache regularly, especially during dry periods, until it is established (usually after a few weeks). Apply a layer of mulch around the base of the plant to help retain moisture and suppress weeds. Avoid overfertilizing, as Agastache generally does not require much additional fertilizer. With proper care, your bare root Agastache should establish itself quickly and reward you with beautiful blooms throughout the summer. × OK

Renowned for its aromatic leaves and long-lasting, colorful flower spikes that persist throughout the summer and into fall, sometimes even until frost, Agastache offers a multitude of benefits for both novice and experienced gardeners. This comprehensive guide will delve into the unique features of Agastache, explore its various aspects, and provide valuable insights into its native habitat, landscaping design tips, and essential planting and care instructions. What is Agastache? Agastache is a genus of aromatic flowering plants belonging to the mint family (Lamiaceae). Most Agastache species are native to North America, with a significant concentration in the southwestern United States and northern Mexico. These plants are renowned for their long-lasting flower spikes and ability to tolerate heat and early frosts. Some species, like A. foeniculum (Anise hyssop), are also used in herbal medicines and teas. Common Names and Varieties Agastache is known by several common names, each highlighting a different characteristic of the plant: Common Name Description Varieties Hummingbird Mint This name emphasizes the plant's popularity with hummingbirds, which are drawn to its nectar-rich flowers. 'Firebird', 'Raspberry Summer', 'Kudos Ambrosia' Anise Hyssop This name refers to the anise scent of some varieties, similar to hyssop. Agastache foeniculum, 'Blue Fortune', 'Black Adder' Giant Hyssop This name points to their resemblance to hyssop but with a larger size. 'Blue Boa', 'Blue Fortune' Fragrant Giant Hyssop This name combines the size and pleasant fragrance of the plant. 'Summer Glow', 'Bolero' Lavender Giant Hyssop This name is specific to varieties with lavender-colored flowers. 'Blue Fortune', 'Little Adder' There are about 30 species of Agastache, with four commonly found in gardens: Agastache foeniculum, Agastache mexicana, Agastache rugosa, and Agastache rupestris. Some popular varieties include: 'Blue Fortune': This hybrid variety features lavender-blue flowers and is known for its hardiness and long bloom time. 'Black Adder': This variety has violet-red flowers and a compact growth habit. 'Firebird': With its coral orange flowers, this variety is a favorite of hummingbirds. 'Golden Jubilee': This variety stands out with its chartreuse-colored foliage. 'Summer Breeze': This variety boasts a long bloom time and a delightful fragrance. 'Blue Boa': Characterized by large, deep purple-blue flowers, a long bloom time, a stiffly upright habit, and excellent vigor. This cultivar is a selection from a breeding line using Agastache rugosa as a parent to provide cold hardiness and wet soil tolerance. In addition to these, the Kudosâ„¢ Agastache series deserves special mention. This series was specifically bred for increased tolerance to moisture and cold, expanding the potential growing range of Agastache and making it suitable for more diverse climates. These hybrids combine the traits of Southwestern US and Mexican species, which tolerate heat and drought, with Agastache rugosa, an Asian species that better tolerates moisture and colder winters. Kudosâ„¢ plants are more compact and tidier, with dense, long-flowering blooms that retain their colorful calyxes even after the flowers fade. Physical Characteristics Agastache plants typically grow between 1 and 3 feet tall, with a similar spread. However, some species can reach up to 6 feet in height. They have an upright, clump-forming habit with sturdy square stems characteristic of the mint family. The leaves are generally lance-shaped with toothed edges and come in various shades of green, gray-green, or gold. When crushed, the leaves release a fragrant aroma, often reminiscent of anise or licorice. For instance, A. rupestris has a unique "root beer" scent. The flowers of Agastache are arranged in dense, terminal spikes, creating a striking display. They come in a wide array of colors, including blue, purple, pink, orange, and white. The individual flowers are tubular and two-lipped, typical of the mint family. Native Habitat Agastache species are predominantly found in dry and often hilly areas of North America, China, and Japan. They thrive in full sun and well-drained soil. Varieties from Mexico and the Southwest US require excellent drainage. Agastache foeniculum, or anise hyssop, is native to prairies, dry upland forested areas, plains, and fields in the upper Midwest and Great Plains of North America. It prefers full sun to partial shade and tolerates a wide range of soils as long as they are well-drained. It is hardy to zones 3-8. Agastache rugosa, or Korean mint, is native to moist grasslands, valleys, and stream banks in China, Vietnam, Laos, Korea, and Japan. Unlike the more drought-tolerant native species, A. rugosa and its hybrids are better suited to the more humid climates of the eastern US.

Fertilizer: Agastache generally does not require additional fertilizer, especially if you amended your soil before planting. Overfertilizing can actually reduce flowering and make the plants leggy. If your plants look pale, a light application of a balanced fertilizer in early spring may be beneficial. Other Care Tips: Deadheading: Regularly deadheading spent flowers will encourage reblooming throughout the summer. Cutting Back: In late fall or early spring, cut back the plant stems to about 4-6 inches above the ground. This will remove old growth and encourage new growth in the spring. Winter Protection: In colder climates (zones 5-6), you can mulch around the base of the plant with a light layer of straw or leaves to protect the roots from winter freezes. However, avoid covering the crown of the plant. By following these simple care tips, you can enjoy the beauty and low-maintenance appeal of Agastache in your garden for many years to come.

Agastache’s Latin Name Pronunciation, Common Names and Botanical Names Agastache's Latin name pronunciation can be a bit of a toss-up, depending on the reference you use. Here is what you need to know: Pronunciation: Preferred: "a-GAH-sta-kee" according to "Dictionary of Plant Names" by Allen Coombes. Alternative: "ag-ah-STAK-ee" mentioned in "Fine Gardening" pronunciation guide. There is no single "correct" way, so either pronunciation is acceptable. Common Names: Agastache has several charming common names that are quite descriptive: Hummingbird Mint: This highlights their popularity with hummingbirds. Anise Hyssop: Refers to the anise scent of some varieties, similar to hyssop. Giant Hyssop: Points to their resemblance to hyssop but larger size. Fragrant Giant Hyssop: Combines the size and pleasant fragrance. Lavender Giant Hyssop: Specific to varieties with lavender-colored flowers. Botanical Names: Agastache is the genus name, but each variety has a specific epithet following it. Here are a couple of examples: Agastache foeniculum: This is the botanical name for anise hyssop. Agastache aurantiaca: This is the botanical name for orange hummingbird mint. So, the next time you come across Agastache, you can confidently pronounce its name (using either a-GAH-sta-kee or ag-ah-STAK-ee) and recognize it by its various common names or full botanical name. Agastache’s Critter, Pest and Disease Resistance Agastache is generally considered a low-maintenance plant that does not attract many pests or diseases. Here is a breakdown of their resistance: Critter Resistance: Deer resistant: Deer tend to leave Agastache alone due to the foliage's somewhat coarse texture and mild anise scent. Rabbit resistant: Rabbits are not particularly attracted to Agastache and will usually leave them be. Pest Resistance: Agastache is relatively pest-resistant, but a few minor pests can occasionally trouble them: Aphids: These tiny, sap-sucking insects can sometimes infest the stems and leaves. You can control them with insecticidal soap or neem oil spray. Spittlebugs: These create foamy masses around themselves on the plant. A strong jet of water can dislodge them, or insecticidal soap can be used for larger infestations. Disease Resistance: Agastache is generally disease-resistant, but there are a couple of potential issues to watch for: Powdery mildew: This fungal disease can cause white powdery spots on the leaves. Improve air circulation by thinning overcrowded plants and avoid overhead watering. In severe cases, a fungicide may be necessary. Root rot: This can occur in poorly drained soils. Ensure the soil drains well and water only when needed. By providing proper care, including well-drained soil, adequate sunlight, and avoiding overwatering, you can help your Agastache thrive and resist pests and diseases. Planting Bare Root Agastache Timing: The best time to plant bare root Agastache depends on your climate zone: Fall planting: Ideally suited for zones 5-7. Plant bare root Agastache in fall, at least 4-6 weeks before the ground freezes. This allows the roots to establish before winter. Early spring planting: For zones 8-10, or if you miss the fall planting window, early spring (as soon as the ground thaws and can be worked) is acceptable. Before Planting: Inspect the bare root Agastache. The roots should be plump and white, not mushy or shriveled. If planting is not happening right away, store the bare root Agastache in a cool, moist place (like a refrigerator) for a short period. Planting: Choose a planting location that receives full sun and has well-drained soil. Agastache will not tolerate soggy conditions. Dig a hole that is twice the width of the root spread of the Agastache. If your soil is heavy clay, amend the planting hole with compost or other organic matter to improve drainage. Gently loosen and spread out the roots of the Agastache plant. Position the plant in the hole so that the crown (the point where the roots and stems meet) sits at soil level. Backfill the hole with soil, tamping it down gently to remove air pockets. Water the plant thoroughly to settle the soil around the roots. After Planting: Water your newly planted Agastache regularly, especially during dry periods, until it is established (usually after a few weeks). Apply a layer of mulch around the base of the plant to help retain moisture and suppress weeds. Avoid overfertilizing, as Agastache generally does not require much additional fertilizer. With proper care, your bare root Agastache should establish itself quickly and reward you with beautiful blooms throughout the summer. × OK

MSRP: Now: $212.20 Choose Options Compare Agastache: The Must-Have Plant for Every Garden Agastache, commonly known as hummingbird mint or hyssop, is a versatile and captivating perennial that deserves a place in every garden. Renowned for its aromatic leaves and long-lasting, colorful flower spikes that persist throughout the summer and into fall, sometimes even until frost, Agastache offers a multitude of benefits for both novice and experienced gardeners. This comprehensive guide will delve into the unique features of Agastache, explore its various aspects, and provide valuable insights into its native habitat, landscaping design tips, and essential planting and care instructions. What is Agastache? Agastache is a genus of aromatic flowering plants belonging to the mint family (Lamiaceae). Most Agastache species are native to North America, with a significant concentration in the southwestern United States and northern Mexico. These plants are renowned for their long-lasting flower spikes and ability to tolerate heat and early frosts. Some species, like A. foeniculum (Anise hyssop), are also used in herbal medicines and teas. Common Names and Varieties Agastache is known by several common names, each highlighting a different characteristic of the plant: Common Name Description Varieties Hummingbird Mint This name emphasizes the plant's popularity with hummingbirds, which are drawn to its nectar-rich flowers. 'Firebird', 'Raspberry Summer', 'Kudos Ambrosia' Anise Hyssop This name refers to the anise scent of some varieties, similar to hyssop. Agastache foeniculum, 'Blue Fortune', 'Black Adder' Giant Hyssop This name points to their resemblance to hyssop but with a larger size. 'Blue Boa', 'Blue Fortune' Fragrant Giant Hyssop This name combines the size and pleasant fragrance of the plant. 'Summer Glow', 'Bolero' Lavender Giant Hyssop This name is specific to varieties with lavender-colored flowers. 'Blue Fortune', 'Little Adder' There are about 30 species of Agastache, with four commonly found in gardens: Agastache foeniculum, Agastache mexicana, Agastache rugosa, and Agastache rupestris. Some popular varieties include: 'Blue Fortune': This hybrid variety features lavender-blue flowers and is known for its hardiness and long bloom time. 'Black Adder': This variety has violet-red flowers and a compact growth habit. 'Firebird': With its coral orange flowers, this variety is a favorite of hummingbirds. 'Golden Jubilee': This variety stands out with its chartreuse-colored foliage. 'Summer Breeze': This variety boasts a long bloom time and a delightful fragrance. 'Blue Boa': Characterized by large, deep purple-blue flowers, a long bloom time, a stiffly upright habit, and excellent vigor. This cultivar is a selection from a breeding line using Agastache rugosa as a parent to provide cold hardiness and wet soil tolerance. In addition to these, the Kudosâ„¢ Agastache series deserves special mention. This series was specifically bred for increased tolerance to moisture and cold, expanding the potential growing range of Agastache and making it suitable for more diverse climates. These hybrids combine the traits of Southwestern US and Mexican species, which tolerate heat and drought, with Agastache rugosa, an Asian species that better tolerates moisture and colder winters. Kudosâ„¢ plants are more compact and tidier, with dense, long-flowering blooms that retain their colorful calyxes even after the flowers fade. Physical Characteristics Agastache plants typically grow between 1 and 3 feet tall, with a similar spread. However, some species can reach up to 6 feet in height. They have an upright, clump-forming habit with sturdy square stems characteristic of the mint family. The leaves are generally lance-shaped with toothed edges and come in various shades of green, gray-green, or gold. When crushed, the leaves release a fragrant aroma, often reminiscent of anise or licorice. For instance, A. rupestris has a unique "root beer" scent. The flowers of Agastache are arranged in dense, terminal spikes, creating a striking display. They come in a wide array of colors, including blue, purple, pink, orange, and white. The individual flowers are tubular and two-lipped, typical of the mint family. Native Habitat Agastache species are predominantly found in dry and often hilly areas of North America, China, and Japan. They thrive in full sun and well-drained soil. Varieties from Mexico and the Southwest US require excellent drainage. Agastache foeniculum, or anise hyssop, is native to prairies, dry upland forested areas, plains, and fields in the upper Midwest and Great Plains of North America. It prefers full sun to partial shade and tolerates a wide range of soils as long as they are well-drained. It is hardy to zones 3-8. Agastache rugosa, or Korean mint, is native to moist grasslands, valleys, and stream banks in China, Vietnam, Laos, Korea, and Japan. Unlike the more drought-tolerant native species, A. rugosa and its hybrids are better suited to the more humid climates of the eastern US. Landscaping Design Tips Agastache's versatility, long blooming period, and ability to grow in both the ground and containers allow for greater flexibility in garden design. It is an excellent choice for various garden designs: Perennial Borders: Agastache adds height and color to perennial borders, especially in mid-to-late summer when many other plants are fading. Its upright habit provides structure and visual interest, while its vibrant flower spikes create focal points within the border. Butterfly Gardens: The nectar-rich flowers of Agastache are a magnet for butterflies, making it an essential component of any butterfly garden. Combine it with other butterfly-friendly plants like Buddleja (butterfly bush), Asclepias (milkweed), and Echinacea (coneflower) to create a haven for these beautiful pollinators. Cottage Gardens: Agastache's informal growth habit and vibrant colors blend seamlessly into cottage gardens. Its long blooming season ensures continuous color throughout the summer and fall, complementing the relaxed and abundant style of cottage gardens. Herb Gardens: Some Agastache species, such as anise hyssop (Agastache foeniculum), have culinary and medicinal uses, making them suitable for herb gardens. The leaves can be used to make tea or add flavor to salads and other dishes. Xeriscapes: Agastache's drought tolerance makes it a valuable addition to xeriscapes or dry gardens. Combine it with other drought-tolerant plants like Lavandula (lavender), Salvia (sage), and Perovskia (Russian sage) to create a water-wise landscape that requires minimal irrigation. Containers: Agastache can be grown in containers, provided they are placed in a sunny location and have adequate drainage. Choose compact varieties for smaller containers and taller varieties for larger pots. When designing with Agastache, consider the following: Color Palette: Agastache flowers come in a wide range of colors, allowing you to create vibrant displays by pairing them with plants that have complementary or contrasting colors. Companion Plants: Agastache combines well with various perennials, including Echinacea (coneflower), Rudbeckia hirta (black-eyed Susan), Sedum (stonecrop), Salvia (sage), Lavandula angustifolia (English lavender), and Crocosmia (Montbretia). Height and Spread: Choose Agastache varieties that fit the scale of your garden, considering their mature height and spread. Planting and Care Agastache is relatively easy to grow and care for, requiring minimal maintenance once established. Here are some essential guidelines: Planting Timing: Plant Agastache in spring after the danger of frost has passed. Location: Choose a sunny site with well-drained soil. Soil Preparation: Loosen the soil and amend it with compost to improve drainage and fertility. Spacing: Space plants 12 to 15 inches apart. Self-Sowing: Agastache readily self-sows, especially in colder climates. If you want to prevent this, deadhead the flowers before they go to seed. Care Watering: Water regularly until plants are established, then water occasionally as needed. Agastache is drought-tolerant once established. Fertilizing: Agastache prefers lean soil and typically does not require fertilizer. Over-fertilization can negatively impact the plant's growth and flowering, causing it to produce fewer blooms and become floppy. Mulching: Mulching is generally not necessary, but a thin layer of pine needles or crushed stone can help retain moisture and suppress weeds. Pruning: Deadhead spent flowers to encourage rebloom. In late winter or early spring, cut back the remaining stems to the ground. Dividing: Divide plants every 3 to 5 years to rejuvenate them. Propagation Agastache can be propagated from seed or cuttings. Seed Propagation: Sow seeds in early spring when the soil temperature is between 55-64°F. Start seeds indoors 4-6 weeks before the last frost or sow directly into the garden after the last frost. Cuttings: Take semi-ripe cuttings in summer. Dip the cut ends in rooting hormone and plant them in a moist potting mix. Keep the cuttings in a warm, humid environment until they root.

Renowned for its aromatic leaves and long-lasting, colorful flower spikes that persist throughout the summer and into fall, sometimes even until frost, Agastache offers a multitude of benefits for both novice and experienced gardeners. This comprehensive guide will delve into the unique features of Agastache, explore its various aspects, and provide valuable insights into its native habitat, landscaping design tips, and essential planting and care instructions. What is Agastache? Agastache is a genus of aromatic flowering plants belonging to the mint family (Lamiaceae). Most Agastache species are native to North America, with a significant concentration in the southwestern United States and northern Mexico. These plants are renowned for their long-lasting flower spikes and ability to tolerate heat and early frosts. Some species, like A. foeniculum (Anise hyssop), are also used in herbal medicines and teas. Common Names and Varieties Agastache is known by several common names, each highlighting a different characteristic of the plant: Common Name Description Varieties Hummingbird Mint This name emphasizes the plant's popularity with hummingbirds, which are drawn to its nectar-rich flowers. 'Firebird', 'Raspberry Summer', 'Kudos Ambrosia' Anise Hyssop This name refers to the anise scent of some varieties, similar to hyssop.

Physical Characteristics Agastache plants typically grow between 1 and 3 feet tall, with a similar spread. However, some species can reach up to 6 feet in height. They have an upright, clump-forming habit with sturdy square stems characteristic of the mint family. The leaves are generally lance-shaped with toothed edges and come in various shades of green, gray-green, or gold. When crushed, the leaves release a fragrant aroma, often reminiscent of anise or licorice. For instance, A. rupestris has a unique "root beer" scent. The flowers of Agastache are arranged in dense, terminal spikes, creating a striking display. They come in a wide array of colors, including blue, purple, pink, orange, and white. The individual flowers are tubular and two-lipped, typical of the mint family. Native Habitat Agastache species are predominantly found in dry and often hilly areas of North America, China, and Japan. They thrive in full sun and well-drained soil. Varieties from Mexico and the Southwest US require excellent drainage. Agastache foeniculum, or anise hyssop, is native to prairies, dry upland forested areas, plains, and fields in the upper Midwest and Great Plains of North America. It prefers full sun to partial shade and tolerates a wide range of soils as long as they are well-drained. It is hardy to zones 3-8. Agastache rugosa, or Korean mint, is native to moist grasslands, valleys, and stream banks in China, Vietnam, Laos, Korea, and Japan. Unlike the more drought-tolerant native species, A. rugosa and its hybrids are better suited to the more humid climates of the eastern US.

Butterfly Gardens: The nectar-rich flowers of Agastache are a magnet for butterflies, making it an essential component of any butterfly garden. Combine it with other butterfly-friendly plants like Buddleja (butterfly bush), Asclepias (milkweed), and Echinacea (coneflower) to create a haven for these beautiful pollinators. Cottage Gardens: Agastache's informal growth habit and vibrant colors blend seamlessly into cottage gardens. Its long blooming season ensures continuous color throughout the summer and fall, complementing the relaxed and abundant style of cottage gardens. Herb Gardens: Some Agastache species, such as anise hyssop (Agastache foeniculum), have culinary and medicinal uses, making them suitable for herb gardens. The leaves can be used to make tea or add flavor to salads and other dishes. Xeriscapes: Agastache's drought tolerance makes it a valuable addition to xeriscapes or dry gardens. Combine it with other drought-tolerant plants like Lavandula (lavender), Salvia (sage), and Perovskia (Russian sage) to create a water-wise landscape that requires minimal irrigation. Containers: Agastache can be grown in containers, provided they are placed in a sunny location and have adequate drainage. Choose compact varieties for smaller containers and taller varieties for larger pots. When designing with Agastache, consider the following: Color Palette: Agastache flowers come in a wide range of colors, allowing you to create vibrant displays by pairing them with plants that have complementary or contrasting colors. Companion Plants: Agastache combines well with various perennials, including Echinacea (coneflower), Rudbeckia hirta (black-eyed Susan), Sedum (stonecrop), Salvia (sage), Lavandula angustifolia (English lavender), and Crocosmia (Montbretia).

Agastache’s Critter, Pest and Disease Resistance Agastache is generally considered a low-maintenance plant that does not attract many pests or diseases. Here is a breakdown of their resistance: Critter Resistance: Deer resistant: Deer tend to leave Agastache alone due to the foliage's somewhat coarse texture and mild anise scent. Rabbit resistant: Rabbits are not particularly attracted to Agastache and will usually leave them be. Pest Resistance: Agastache is relatively pest-resistant, but a few minor pests can occasionally trouble them: Aphids: These tiny, sap-sucking insects can sometimes infest the stems and leaves. You can control them with insecticidal soap or neem oil spray. Spittlebugs: These create foamy masses around themselves on the plant. A strong jet of water can dislodge them, or insecticidal soap can be used for larger infestations. Disease Resistance: Agastache is generally disease-resistant, but there are a couple of potential issues to watch for: Powdery mildew: This fungal disease can cause white powdery spots on the leaves. Improve air circulation by thinning overcrowded plants and avoid overhead watering. In severe cases, a fungicide may be necessary. Root rot: This can occur in poorly drained soils. Ensure the soil drains well and water only when needed. By providing proper care, including well-drained soil, adequate sunlight, and avoiding overwatering, you can help your Agastache thrive and resist pests and diseases. Planting Bare Root Agastache Timing: The best time to plant bare root Agastache depends on your climate zone: Fall planting: Ideally suited for zones 5-7. Plant bare root Agastache in fall, at least 4-6 weeks before the ground freezes. This allows the roots to establish before winter. Early spring planting: For zones 8-10, or if you miss the fall planting window, early spring (as soon as the ground thaws and can be worked) is acceptable. Before Planting: Inspect the bare root Agastache. The roots should be plump and white, not mushy or shriveled. If planting is not happening right away, store the bare root Agastache in a cool, moist place (like a refrigerator) for a short period. Planting: Choose a planting location that receives full sun and has well-drained soil. Agastache will not tolerate soggy conditions. Dig a hole that is twice the width of the root spread of the Agastache. If your soil is heavy clay, amend the planting hole with compost or other organic matter to improve drainage. Gently loosen and spread out the roots of the Agastache plant. Position the plant in the hole so that the crown (the point where the roots and stems meet) sits at soil level. Backfill the hole with soil, tamping it down gently to remove air pockets. Water the plant thoroughly to settle the soil around the roots. After Planting: Water your newly planted Agastache regularly, especially during dry periods, until it is established (usually after a few weeks). Apply a layer of mulch around the base of the plant to help retain moisture and suppress weeds. Avoid overfertilizing, as Agastache generally does not require much additional fertilizer. With proper care, your bare root Agastache should establish itself quickly and reward you with beautiful blooms throughout the summer. × OK

Planting Bare Root Agastache Timing: The best time to plant bare root Agastache depends on your climate zone: Fall planting: Ideally suited for zones 5-7. Plant bare root Agastache in fall, at least 4-6 weeks before the ground freezes. This allows the roots to establish before winter. Early spring planting: For zones 8-10, or if you miss the fall planting window, early spring (as soon as the ground thaws and can be worked) is acceptable. Before Planting: Inspect the bare root Agastache. The roots should be plump and white, not mushy or shriveled. If planting is not happening right away, store the bare root Agastache in a cool, moist place (like a refrigerator) for a short period. Planting: Choose a planting location that receives full sun and has well-drained soil. Agastache will not tolerate soggy conditions. Dig a hole that is twice the width of the root spread of the Agastache. If your soil is heavy clay, amend the planting hole with compost or other organic matter to improve drainage. Gently loosen and spread out the roots of the Agastache plant. Position the plant in the hole so that the crown (the point where the roots and stems meet) sits at soil level. Backfill the hole with soil, tamping it down gently to remove air pockets. Water the plant thoroughly to settle the soil around the roots. After Planting: Water your newly planted Agastache regularly, especially during dry periods, until it is established (usually after a few weeks). Apply a layer of mulch around the base of the plant to help retain moisture and suppress weeds. Avoid overfertilizing, as Agastache generally does not require much additional fertilizer. With proper care, your bare root Agastache should establish itself quickly and reward you with beautiful blooms throughout the summer. × OK

Renowned for its aromatic leaves and long-lasting, colorful flower spikes that persist throughout the summer and into fall, sometimes even until frost, Agastache offers a multitude of benefits for both novice and experienced gardeners. This comprehensive guide will delve into the unique features of Agastache, explore its various aspects, and provide valuable insights into its native habitat, landscaping design tips, and essential planting and care instructions. What is Agastache? Agastache is a genus of aromatic flowering plants belonging to the mint family (Lamiaceae). Most Agastache species are native to North America, with a significant concentration in the southwestern United States and northern Mexico. These plants are renowned for their long-lasting flower spikes and ability to tolerate heat and early frosts. Some species, like A. foeniculum (Anise hyssop), are also used in herbal medicines and teas. Common Names and Varieties Agastache is known by several common names, each highlighting a different characteristic of the plant: Common Name Description Varieties Hummingbird Mint This name emphasizes the plant's popularity with hummingbirds, which are drawn to its nectar-rich flowers. 'Firebird', 'Raspberry Summer', 'Kudos Ambrosia' Anise Hyssop This name refers to the anise scent of some varieties, similar to hyssop. Agastache foeniculum, 'Blue Fortune', 'Black Adder' Giant Hyssop This name points to their resemblance to hyssop but with a larger size. 'Blue Boa', 'Blue Fortune' Fragrant Giant Hyssop This name combines the size and pleasant fragrance of the plant. 'Summer Glow', 'Bolero' Lavender Giant Hyssop This name is specific to varieties with lavender-colored flowers. 'Blue Fortune', 'Little Adder' There are about 30 species of Agastache, with four commonly found in gardens: Agastache foeniculum, Agastache mexicana, Agastache rugosa, and Agastache rupestris. Some popular varieties include: 'Blue Fortune': This hybrid variety features lavender-blue flowers and is known for its hardiness and long bloom time. 'Black Adder': This variety has violet-red flowers and a compact growth habit. 'Firebird': With its coral orange flowers, this variety is a favorite of hummingbirds. 'Golden Jubilee': This variety stands out with its chartreuse-colored foliage. 'Summer Breeze': This variety boasts a long bloom time and a delightful fragrance. 'Blue Boa': Characterized by large, deep purple-blue flowers, a long bloom time, a stiffly upright habit, and excellent vigor. This cultivar is a selection from a breeding line using Agastache rugosa as a parent to provide cold hardiness and wet soil tolerance. In addition to these, the Kudosâ„¢ Agastache series deserves special mention. This series was specifically bred for increased tolerance to moisture and cold, expanding the potential growing range of Agastache and making it suitable for more diverse climates. These hybrids combine the traits of Southwestern US and Mexican species, which tolerate heat and drought, with Agastache rugosa, an Asian species that better tolerates moisture and colder winters. Kudosâ„¢ plants are more compact and tidier, with dense, long-flowering blooms that retain their colorful calyxes even after the flowers fade. Physical Characteristics Agastache plants typically grow between 1 and 3 feet tall, with a similar spread. However, some species can reach up to 6 feet in height. They have an upright, clump-forming habit with sturdy square stems characteristic of the mint family. The leaves are generally lance-shaped with toothed edges and come in various shades of green, gray-green, or gold. When crushed, the leaves release a fragrant aroma, often reminiscent of anise or licorice. For instance, A. rupestris has a unique "root beer" scent. The flowers of Agastache are arranged in dense, terminal spikes, creating a striking display. They come in a wide array of colors, including blue, purple, pink, orange, and white. The individual flowers are tubular and two-lipped, typical of the mint family. Native Habitat Agastache species are predominantly found in dry and often hilly areas of North America, China, and Japan. They thrive in full sun and well-drained soil. Varieties from Mexico and the Southwest US require excellent drainage. Agastache foeniculum, or anise hyssop, is native to prairies, dry upland forested areas, plains, and fields in the upper Midwest and Great Plains of North America. It prefers full sun to partial shade and tolerates a wide range of soils as long as they are well-drained. It is hardy to zones 3-8. Agastache rugosa, or Korean mint, is native to moist grasslands, valleys, and stream banks in China, Vietnam, Laos, Korea, and Japan. Unlike the more drought-tolerant native species, A. rugosa and its hybrids are better suited to the more humid climates of the eastern US. Landscaping Design Tips Agastache's versatility, long blooming period, and ability to grow in both the ground and containers allow for greater flexibility in garden design. It is an excellent choice for various garden designs: Perennial Borders: Agastache adds height and color to perennial borders, especially in mid-to-late summer when many other plants are fading. Its upright habit provides structure and visual interest, while its vibrant flower spikes create focal points within the border. Butterfly Gardens: The nectar-rich flowers of Agastache are a magnet for butterflies, making it an essential component of any butterfly garden. Combine it with other butterfly-friendly plants like Buddleja (butterfly bush), Asclepias (milkweed), and Echinacea (coneflower) to create a haven for these beautiful pollinators. Cottage Gardens: Agastache's informal growth habit and vibrant colors blend seamlessly into cottage gardens. Its long blooming season ensures continuous color throughout the summer and fall, complementing the relaxed and abundant style of cottage gardens. Herb Gardens: Some Agastache species, such as anise hyssop (Agastache foeniculum), have culinary and medicinal uses, making them suitable for herb gardens. The leaves can be used to make tea or add flavor to salads and other dishes. Xeriscapes: Agastache's drought tolerance makes it a valuable addition to xeriscapes or dry gardens. Combine it with other drought-tolerant plants like Lavandula (lavender), Salvia (sage), and Perovskia (Russian sage) to create a water-wise landscape that requires minimal irrigation. Containers: Agastache can be grown in containers, provided they are placed in a sunny location and have adequate drainage. Choose compact varieties for smaller containers and taller varieties for larger pots. When designing with Agastache, consider the following: Color Palette: Agastache flowers come in a wide range of colors, allowing you to create vibrant displays by pairing them with plants that have complementary or contrasting colors. Companion Plants: Agastache combines well with various perennials, including Echinacea (coneflower), Rudbeckia hirta (black-eyed Susan), Sedum (stonecrop), Salvia (sage), Lavandula angustifolia (English lavender), and Crocosmia (Montbretia). Height and Spread: Choose Agastache varieties that fit the scale of your garden, considering their mature height and spread. Planting and Care Agastache is relatively easy to grow and care for, requiring minimal maintenance once established. Here are some essential guidelines: Planting Timing: Plant Agastache in spring after the danger of frost has passed. Location: Choose a sunny site with well-drained soil. Soil Preparation: Loosen the soil and amend it with compost to improve drainage and fertility. Spacing: Space plants 12 to 15 inches apart.

So, the next time you come across Agastache, you can confidently pronounce its name (using either a-GAH-sta-kee or ag-ah-STAK-ee) and recognize it by its various common names or full botanical name. Agastache’s Critter, Pest and Disease Resistance Agastache is generally considered a low-maintenance plant that does not attract many pests or diseases. Here is a breakdown of their resistance: Critter Resistance: Deer resistant: Deer tend to leave Agastache alone due to the foliage's somewhat coarse texture and mild anise scent. Rabbit resistant: Rabbits are not particularly attracted to Agastache and will usually leave them be. Pest Resistance: Agastache is relatively pest-resistant, but a few minor pests can occasionally trouble them: Aphids: These tiny, sap-sucking insects can sometimes infest the stems and leaves. You can control them with insecticidal soap or neem oil spray. Spittlebugs: These create foamy masses around themselves on the plant. A strong jet of water can dislodge them, or insecticidal soap can be used for larger infestations. Disease Resistance: Agastache is generally disease-resistant, but there are a couple of potential issues to watch for: Powdery mildew: This fungal disease can cause white powdery spots on the leaves. Improve air circulation by thinning overcrowded plants and avoid overhead watering. In severe cases, a fungicide may be necessary. Root rot: This can occur in poorly drained soils. Ensure the soil drains well and water only when needed. By providing proper care, including well-drained soil, adequate sunlight, and avoiding overwatering, you can help your Agastache thrive and resist pests and diseases. Planting Bare Root Agastache Timing: The best time to plant bare root Agastache depends on your climate zone: Fall planting: Ideally suited for zones 5-7. Plant bare root Agastache in fall, at least 4-6 weeks before the ground freezes. This allows the roots to establish before winter. Early spring planting: For zones 8-10, or if you miss the fall planting window, early spring (as soon as the ground thaws and can be worked) is acceptable. Before Planting: Inspect the bare root Agastache. The roots should be plump and white, not mushy or shriveled. If planting is not happening right away, store the bare root Agastache in a cool, moist place (like a refrigerator) for a short period. Planting: Choose a planting location that receives full sun and has well-drained soil. Agastache will not tolerate soggy conditions. Dig a hole that is twice the width of the root spread of the Agastache. If your soil is heavy clay, amend the planting hole with compost or other organic matter to improve drainage. Gently loosen and spread out the roots of the Agastache plant. Position the plant in the hole so that the crown (the point where the roots and stems meet) sits at soil level. Backfill the hole with soil, tamping it down gently to remove air pockets. Water the plant thoroughly to settle the soil around the roots. After Planting: Water your newly planted Agastache regularly, especially during dry periods, until it is established (usually after a few weeks). Apply a layer of mulch around the base of the plant to help retain moisture and suppress weeds. Avoid overfertilizing, as Agastache generally does not require much additional fertilizer. With proper care, your bare root Agastache should establish itself quickly and reward you with beautiful blooms throughout the summer. × OK

Agastache’s Critter, Pest and Disease Resistance Agastache is generally considered a low-maintenance plant that does not attract many pests or diseases. Here is a breakdown of their resistance: Critter Resistance: Deer resistant: Deer tend to leave Agastache alone due to the foliage's somewhat coarse texture and mild anise scent. Rabbit resistant: Rabbits are not particularly attracted to Agastache and will usually leave them be. Pest Resistance: Agastache is relatively pest-resistant, but a few minor pests can occasionally trouble them: Aphids: These tiny, sap-sucking insects can sometimes infest the stems and leaves. You can control them with insecticidal soap or neem oil spray. Spittlebugs: These create foamy masses around themselves on the plant. A strong jet of water can dislodge them, or insecticidal soap can be used for larger infestations. Disease Resistance: Agastache is generally disease-resistant, but there are a couple of potential issues to watch for: Powdery mildew: This fungal disease can cause white powdery spots on the leaves. Improve air circulation by thinning overcrowded plants and avoid overhead watering. In severe cases, a fungicide may be necessary. Root rot: This can occur in poorly drained soils. Ensure the soil drains well and water only when needed. By providing proper care, including well-drained soil, adequate sunlight, and avoiding overwatering, you can help your Agastache thrive and resist pests and diseases. Planting Bare Root Agastache Timing: The best time to plant bare root Agastache depends on your climate zone: Fall planting: Ideally suited for zones 5-7. Plant bare root Agastache in fall, at least 4-6 weeks before the ground freezes. This allows the roots to establish before winter. Early spring planting: For zones 8-10, or if you miss the fall planting window, early spring (as soon as the ground thaws and can be worked) is acceptable. Before Planting: Inspect the bare root Agastache. The roots should be plump and white, not mushy or shriveled. If planting is not happening right away, store the bare root Agastache in a cool, moist place (like a refrigerator) for a short period. Planting: Choose a planting location that receives full sun and has well-drained soil. Agastache will not tolerate soggy conditions. Dig a hole that is twice the width of the root spread of the Agastache. If your soil is heavy clay, amend the planting hole with compost or other organic matter to improve drainage. Gently loosen and spread out the roots of the Agastache plant. Position the plant in the hole so that the crown (the point where the roots and stems meet) sits at soil level. Backfill the hole with soil, tamping it down gently to remove air pockets. Water the plant thoroughly to settle the soil around the roots. After Planting: Water your newly planted Agastache regularly, especially during dry periods, until it is established (usually after a few weeks). Apply a layer of mulch around the base of the plant to help retain moisture and suppress weeds. Avoid overfertilizing, as Agastache generally does not require much additional fertilizer. With proper care, your bare root Agastache should establish itself quickly and reward you with beautiful blooms throughout the summer. × OK

Renowned for its aromatic leaves and long-lasting, colorful flower spikes that persist throughout the summer and into fall, sometimes even until frost, Agastache offers a multitude of benefits for both novice and experienced gardeners. This comprehensive guide will delve into the unique features of Agastache, explore its various aspects, and provide valuable insights into its native habitat, landscaping design tips, and essential planting and care instructions. What is Agastache? Agastache is a genus of aromatic flowering plants belonging to the mint family (Lamiaceae). Most Agastache species are native to North America, with a significant concentration in the southwestern United States and northern Mexico. These plants are renowned for their long-lasting flower spikes and ability to tolerate heat and early frosts. Some species, like A. foeniculum (Anise hyssop), are also used in herbal medicines and teas. Common Names and Varieties Agastache is known by several common names, each highlighting a different characteristic of the plant: Common Name Description Varieties Hummingbird Mint This name emphasizes the plant's popularity with hummingbirds, which are drawn to its nectar-rich flowers. 'Firebird', 'Raspberry Summer', 'Kudos Ambrosia' Anise Hyssop This name refers to the anise scent of some varieties, similar to hyssop. Agastache foeniculum, 'Blue Fortune', 'Black Adder' Giant Hyssop This name points to their resemblance to hyssop but with a larger size. 'Blue Boa', 'Blue Fortune' Fragrant Giant Hyssop This name combines the size and pleasant fragrance of the plant. 'Summer Glow', 'Bolero' Lavender Giant Hyssop This name is specific to varieties with lavender-colored flowers. 'Blue Fortune', 'Little Adder' There are about 30 species of Agastache, with four commonly found in gardens: Agastache foeniculum, Agastache mexicana, Agastache rugosa, and Agastache rupestris. Some popular varieties include: 'Blue Fortune': This hybrid variety features lavender-blue flowers and is known for its hardiness and long bloom time. 'Black Adder': This variety has violet-red flowers and a compact growth habit. 'Firebird': With its coral orange flowers, this variety is a favorite of hummingbirds. 'Golden Jubilee': This variety stands out with its chartreuse-colored foliage. 'Summer Breeze': This variety boasts a long bloom time and a delightful fragrance. 'Blue Boa': Characterized by large, deep purple-blue flowers, a long bloom time, a stiffly upright habit, and excellent vigor. This cultivar is a selection from a breeding line using Agastache rugosa as a parent to provide cold hardiness and wet soil tolerance. In addition to these, the Kudosâ„¢ Agastache series deserves special mention. This series was specifically bred for increased tolerance to moisture and cold, expanding the potential growing range of Agastache and making it suitable for more diverse climates. These hybrids combine the traits of Southwestern US and Mexican species, which tolerate heat and drought, with Agastache rugosa, an Asian species that better tolerates moisture and colder winters. Kudosâ„¢ plants are more compact and tidier, with dense, long-flowering blooms that retain their colorful calyxes even after the flowers fade. Physical Characteristics Agastache plants typically grow between 1 and 3 feet tall, with a similar spread. However, some species can reach up to 6 feet in height. They have an upright, clump-forming habit with sturdy square stems characteristic of the mint family. The leaves are generally lance-shaped with toothed edges and come in various shades of green, gray-green, or gold. When crushed, the leaves release a fragrant aroma, often reminiscent of anise or licorice. For instance, A. rupestris has a unique "root beer" scent. The flowers of Agastache are arranged in dense, terminal spikes, creating a striking display. They come in a wide array of colors, including blue, purple, pink, orange, and white. The individual flowers are tubular and two-lipped, typical of the mint family. Native Habitat Agastache species are predominantly found in dry and often hilly areas of North America, China, and Japan. They thrive in full sun and well-drained soil. Varieties from Mexico and the Southwest US require excellent drainage. Agastache foeniculum, or anise hyssop, is native to prairies, dry upland forested areas, plains, and fields in the upper Midwest and Great Plains of North America. It prefers full sun to partial shade and tolerates a wide range of soils as long as they are well-drained. It is hardy to zones 3-8. Agastache rugosa, or Korean mint, is native to moist grasslands, valleys, and stream banks in China, Vietnam, Laos, Korea, and Japan. Unlike the more drought-tolerant native species, A. rugosa and its hybrids are better suited to the more humid climates of the eastern US.

Here is what you need to know: Pronunciation: Preferred: "a-GAH-sta-kee" according to "Dictionary of Plant Names" by Allen Coombes. Alternative: "ag-ah-STAK-ee" mentioned in "Fine Gardening" pronunciation guide. There is no single "correct" way, so either pronunciation is acceptable. Common Names: Agastache has several charming common names that are quite descriptive: Hummingbird Mint: This highlights their popularity with hummingbirds. Anise Hyssop: Refers to the anise scent of some varieties, similar to hyssop. Giant Hyssop: Points to their resemblance to hyssop but larger size. Fragrant Giant Hyssop: Combines the size and pleasant fragrance. Lavender Giant Hyssop: Specific to varieties with lavender-colored flowers. Botanical Names: Agastache is the genus name, but each variety has a specific epithet following it. Here are a couple of examples: Agastache foeniculum: This is the botanical name for anise hyssop. Agastache aurantiaca: This is the botanical name for orange hummingbird mint. So, the next time you come across Agastache, you can confidently pronounce its name (using either a-GAH-sta-kee or ag-ah-STAK-ee) and recognize it by its various common names or full botanical name. Agastache’s Critter, Pest and Disease Resistance Agastache is generally considered a low-maintenance plant that does not attract many pests or diseases. Here is a breakdown of their resistance: Critter Resistance: Deer resistant: Deer tend to leave Agastache alone due to the foliage's somewhat coarse texture and mild anise scent. Rabbit resistant: Rabbits are not particularly attracted to Agastache and will usually leave them be. Pest Resistance: Agastache is relatively pest-resistant, but a few minor pests can occasionally trouble them: Aphids: These tiny, sap-sucking insects can sometimes infest the stems and leaves. You can control them with insecticidal soap or neem oil spray. Spittlebugs: These create foamy masses around themselves on the plant. A strong jet of water can dislodge them, or insecticidal soap can be used for larger infestations. Disease Resistance: Agastache is generally disease-resistant, but there are a couple of potential issues to watch for: Powdery mildew: This fungal disease can cause white powdery spots on the leaves. Improve air circulation by thinning overcrowded plants and avoid overhead watering. In severe cases, a fungicide may be necessary. Root rot: This can occur in poorly drained soils. Ensure the soil drains well and water only when needed. By providing proper care, including well-drained soil, adequate sunlight, and avoiding overwatering, you can help your Agastache thrive and resist pests and diseases. Planting Bare Root Agastache Timing: The best time to plant bare root Agastache depends on your climate zone: Fall planting: Ideally suited for zones 5-7. Plant bare root Agastache in fall, at least 4-6 weeks before the ground freezes. This allows the roots to establish before winter. Early spring planting: For zones 8-10, or if you miss the fall planting window, early spring (as soon as the ground thaws and can be worked) is acceptable. Before Planting: Inspect the bare root Agastache. The roots should be plump and white, not mushy or shriveled. If planting is not happening right away, store the bare root Agastache in a cool, moist place (like a refrigerator) for a short period. Planting: Choose a planting location that receives full sun and has well-drained soil. Agastache will not tolerate soggy conditions. Dig a hole that is twice the width of the root spread of the Agastache. If your soil is heavy clay, amend the planting hole with compost or other organic matter to improve drainage. Gently loosen and spread out the roots of the Agastache plant. Position the plant in the hole so that the crown (the point where the roots and stems meet) sits at soil level. Backfill the hole with soil, tamping it down gently to remove air pockets. Water the plant thoroughly to settle the soil around the roots. After Planting: Water your newly planted Agastache regularly, especially during dry periods, until it is established (usually after a few weeks). Apply a layer of mulch around the base of the plant to help retain moisture and suppress weeds. Avoid overfertilizing, as Agastache generally does not require much additional fertilizer. With proper care, your bare root Agastache should establish itself quickly and reward you with beautiful blooms throughout the summer. × OK

Renowned for its aromatic leaves and long-lasting, colorful flower spikes that persist throughout the summer and into fall, sometimes even until frost, Agastache offers a multitude of benefits for both novice and experienced gardeners. This comprehensive guide will delve into the unique features of Agastache, explore its various aspects, and provide valuable insights into its native habitat, landscaping design tips, and essential planting and care instructions. What is Agastache? Agastache is a genus of aromatic flowering plants belonging to the mint family (Lamiaceae). Most Agastache species are native to North America, with a significant concentration in the southwestern United States and northern Mexico. These plants are renowned for their long-lasting flower spikes and ability to tolerate heat and early frosts. Some species, like A. foeniculum (Anise hyssop), are also used in herbal medicines and teas. Common Names and Varieties Agastache is known by several common names, each highlighting a different characteristic of the plant: Common Name Description Varieties Hummingbird Mint This name emphasizes the plant's popularity with hummingbirds, which are drawn to its nectar-rich flowers.

'Blue Boa', 'Blue Fortune' Fragrant Giant Hyssop This name combines the size and pleasant fragrance of the plant. 'Summer Glow', 'Bolero' Lavender Giant Hyssop This name is specific to varieties with lavender-colored flowers. 'Blue Fortune', 'Little Adder' There are about 30 species of Agastache, with four commonly found in gardens: Agastache foeniculum, Agastache mexicana, Agastache rugosa, and Agastache rupestris. Some popular varieties include: 'Blue Fortune': This hybrid variety features lavender-blue flowers and is known for its hardiness and long bloom time. 'Black Adder': This variety has violet-red flowers and a compact growth habit. 'Firebird': With its coral orange flowers, this variety is a favorite of hummingbirds. 'Golden Jubilee': This variety stands out with its chartreuse-colored foliage. 'Summer Breeze': This variety boasts a long bloom time and a delightful fragrance. 'Blue Boa': Characterized by large, deep purple-blue flowers, a long bloom time, a stiffly upright habit, and excellent vigor. This cultivar is a selection from a breeding line using Agastache rugosa as a parent to provide cold hardiness and wet soil tolerance. In addition to these, the Kudosâ„¢ Agastache series deserves special mention. This series was specifically bred for increased tolerance to moisture and cold, expanding the potential growing range of Agastache and making it suitable for more diverse climates. These hybrids combine the traits of Southwestern US and Mexican species, which tolerate heat and drought, with Agastache rugosa, an Asian species that better tolerates moisture and colder winters. Kudosâ„¢ plants are more compact and tidier, with dense, long-flowering blooms that retain their colorful calyxes even after the flowers fade. Physical Characteristics Agastache plants typically grow between 1 and 3 feet tall, with a similar spread. However, some species can reach up to 6 feet in height. They have an upright, clump-forming habit with sturdy square stems characteristic of the mint family. The leaves are generally lance-shaped with toothed edges and come in various shades of green, gray-green, or gold. When crushed, the leaves release a fragrant aroma, often reminiscent of anise or licorice. For instance, A. rupestris has a unique "root beer" scent. The flowers of Agastache are arranged in dense, terminal spikes, creating a striking display. They come in a wide array of colors, including blue, purple, pink, orange, and white. The individual flowers are tubular and two-lipped, typical of the mint family. Native Habitat Agastache species are predominantly found in dry and often hilly areas of North America, China, and Japan. They thrive in full sun and well-drained soil. Varieties from Mexico and the Southwest US require excellent drainage. Agastache foeniculum, or anise hyssop, is native to prairies, dry upland forested areas, plains, and fields in the upper Midwest and Great Plains of North America. It prefers full sun to partial shade and tolerates a wide range of soils as long as they are well-drained. It is hardy to zones 3-8. Agastache rugosa, or Korean mint, is native to moist grasslands, valleys, and stream banks in China, Vietnam, Laos, Korea, and Japan. Unlike the more drought-tolerant native species, A. rugosa and its hybrids are better suited to the more humid climates of the eastern US.

Agastache’s Critter, Pest and Disease Resistance Agastache is generally considered a low-maintenance plant that does not attract many pests or diseases. Here is a breakdown of their resistance: Critter Resistance: Deer resistant: Deer tend to leave Agastache alone due to the foliage's somewhat coarse texture and mild anise scent. Rabbit resistant: Rabbits are not particularly attracted to Agastache and will usually leave them be. Pest Resistance: Agastache is relatively pest-resistant, but a few minor pests can occasionally trouble them: Aphids: These tiny, sap-sucking insects can sometimes infest the stems and leaves. You can control them with insecticidal soap or neem oil spray. Spittlebugs: These create foamy masses around themselves on the plant. A strong jet of water can dislodge them, or insecticidal soap can be used for larger infestations. Disease Resistance: Agastache is generally disease-resistant, but there are a couple of potential issues to watch for: Powdery mildew: This fungal disease can cause white powdery spots on the leaves. Improve air circulation by thinning overcrowded plants and avoid overhead watering. In severe cases, a fungicide may be necessary. Root rot: This can occur in poorly drained soils. Ensure the soil drains well and water only when needed. By providing proper care, including well-drained soil, adequate sunlight, and avoiding overwatering, you can help your Agastache thrive and resist pests and diseases. Planting Bare Root Agastache Timing: The best time to plant bare root Agastache depends on your climate zone: Fall planting: Ideally suited for zones 5-7. Plant bare root Agastache in fall, at least 4-6 weeks before the ground freezes. This allows the roots to establish before winter. Early spring planting: For zones 8-10, or if you miss the fall planting window, early spring (as soon as the ground thaws and can be worked) is acceptable. Before Planting: Inspect the bare root Agastache. The roots should be plump and white, not mushy or shriveled. If planting is not happening right away, store the bare root Agastache in a cool, moist place (like a refrigerator) for a short period. Planting: Choose a planting location that receives full sun and has well-drained soil. Agastache will not tolerate soggy conditions. Dig a hole that is twice the width of the root spread of the Agastache. If your soil is heavy clay, amend the planting hole with compost or other organic matter to improve drainage. Gently loosen and spread out the roots of the Agastache plant. Position the plant in the hole so that the crown (the point where the roots and stems meet) sits at soil level. Backfill the hole with soil, tamping it down gently to remove air pockets. Water the plant thoroughly to settle the soil around the roots. After Planting: Water your newly planted Agastache regularly, especially during dry periods, until it is established (usually after a few weeks). Apply a layer of mulch around the base of the plant to help retain moisture and suppress weeds. Avoid overfertilizing, as Agastache generally does not require much additional fertilizer. With proper care, your bare root Agastache should establish itself quickly and reward you with beautiful blooms throughout the summer.

This comprehensive guide will delve into the unique features of Agastache, explore its various aspects, and provide valuable insights into its native habitat, landscaping design tips, and essential planting and care instructions. What is Agastache? Agastache is a genus of aromatic flowering plants belonging to the mint family (Lamiaceae). Most Agastache species are native to North America, with a significant concentration in the southwestern United States and northern Mexico. These plants are renowned for their long-lasting flower spikes and ability to tolerate heat and early frosts. Some species, like A. foeniculum (Anise hyssop), are also used in herbal medicines and teas. Common Names and Varieties Agastache is known by several common names, each highlighting a different characteristic of the plant: Common Name Description Varieties Hummingbird Mint This name emphasizes the plant's popularity with hummingbirds, which are drawn to its nectar-rich flowers. 'Firebird', 'Raspberry Summer', 'Kudos Ambrosia' Anise Hyssop This name refers to the anise scent of some varieties, similar to hyssop.

'Blue Boa', 'Blue Fortune' Fragrant Giant Hyssop This name combines the size and pleasant fragrance of the plant. 'Summer Glow', 'Bolero' Lavender Giant Hyssop This name is specific to varieties with lavender-colored flowers. 'Blue Fortune', 'Little Adder' There are about 30 species of Agastache, with four commonly found in gardens: Agastache foeniculum, Agastache mexicana, Agastache rugosa, and Agastache rupestris. Some popular varieties include: 'Blue Fortune': This hybrid variety features lavender-blue flowers and is known for its hardiness and long bloom time. 'Black Adder': This variety has violet-red flowers and a compact growth habit. 'Firebird': With its coral orange flowers, this variety is a favorite of hummingbirds. 'Golden Jubilee': This variety stands out with its chartreuse-colored foliage. 'Summer Breeze': This variety boasts a long bloom time and a delightful fragrance. 'Blue Boa': Characterized by large, deep purple-blue flowers, a long bloom time, a stiffly upright habit, and excellent vigor. This cultivar is a selection from a breeding line using Agastache rugosa as a parent to provide cold hardiness and wet soil tolerance. In addition to these, the Kudosâ„¢ Agastache series deserves special mention. This series was specifically bred for increased tolerance to moisture and cold, expanding the potential growing range of Agastache and making it suitable for more diverse climates. These hybrids combine the traits of Southwestern US and Mexican species, which tolerate heat and drought, with Agastache rugosa, an Asian species that better tolerates moisture and colder winters. Kudosâ„¢ plants are more compact and tidier, with dense, long-flowering blooms that retain their colorful calyxes even after the flowers fade. Physical Characteristics Agastache plants typically grow between 1 and 3 feet tall, with a similar spread. However, some species can reach up to 6 feet in height. They have an upright, clump-forming habit with sturdy square stems characteristic of the mint family. The leaves are generally lance-shaped with toothed edges and come in various shades of green, gray-green, or gold. When crushed, the leaves release a fragrant aroma, often reminiscent of anise or licorice. For instance, A. rupestris has a unique "root beer" scent. The flowers of Agastache are arranged in dense, terminal spikes, creating a striking display. They come in a wide array of colors, including blue, purple, pink, orange, and white. The individual flowers are tubular and two-lipped, typical of the mint family. Native Habitat Agastache species are predominantly found in dry and often hilly areas of North America, China, and Japan. They thrive in full sun and well-drained soil. Varieties from Mexico and the Southwest US require excellent drainage. Agastache foeniculum, or anise hyssop, is native to prairies, dry upland forested areas, plains, and fields in the upper Midwest and Great Plains of North America. It prefers full sun to partial shade and tolerates a wide range of soils as long as they are well-drained. It is hardy to zones 3-8. Agastache rugosa, or Korean mint, is native to moist grasslands, valleys, and stream banks in China, Vietnam, Laos, Korea, and Japan. Unlike the more drought-tolerant native species, A. rugosa and its hybrids are better suited to the more humid climates of the eastern US. Landscaping Design Tips Agastache's versatility, long blooming period, and ability to grow in both the ground and containers allow for greater flexibility in garden design.
