    Echinops, also known as globe thistle, is a genus of flowering plants in the daisy family Asteraceae. They are native to Europe, Asia, and Africa.

    Echinops are prized for their unique, globe-shaped flower heads, which are composed of many tiny, densely packed florets. These flower heads are typically blue or white, and they sit atop tall, sturdy stems that can reach heights of 2-4 feet. The plants have spiny, thistle-like foliage that adds to their visual interest.

    Echinops are relatively low-maintenance plants that are well-suited for sunny borders and wildflower gardens. They are drought-tolerant and attract pollinators like bees and butterflies. The flowers can also be dried and used in arrangements.

    Some popular species of Echinops include:

    • Echinops ritro: This is the most common species, with steel-blue flower heads.
    • Echinops sphaerocephalus: This species has larger, white flower heads.
    • Echinops bannaticus 'Taplow Blue': This cultivar has deep blue flower heads and is known for its long blooming period.

    If you are looking for a unique and eye-catching addition to your garden, Echinops is a great choice!

    Echinops FAQ

    Here is a breakdown of the taxonomy for the Echinops genus, from broadest to most specific:

    • Kingdom: Plantae (Plants)
    • Subkingdom: Tracheobionta (Vascular plants - they have specialized tissues for transporting water and nutrients)
    • Superdivision: Spermatophyta (Seed plants - they reproduce through seeds)
    • Division: Magnoliophyta (Flowering plants)
    • Class: Magnoliopsida (Dicotyledons - they have two seed leaves)
    • Subclass: Asteridae
    • Order: Asterales (The order that includes the Aster, or daisy, family)
    • Family: Asteraceae (The Aster family, also known as Compositae. This is one of the largest plant families and includes sunflowers, daisies, and thistles)
    • Subfamily: Carduoideae (The thistle subfamily)
    • Tribe: Cardueae (The tribe that includes thistles)
    • Genus: Echinops (The globe thistles)

    Within the Echinops genus, there are over 130 recognized species.

    Let us delve into the fascinating morphology of Echinops, those captivating globe thistles! Here is a description of their key physical features:

    Overall Form:

    • Herbaceous Perennials: Most Echinops are herbaceous, meaning their above-ground growth dies back in winter, with the roots remaining alive to sprout again in spring. They typically have an upright growth habit.
    • Height: Depending on the species and growing conditions, Echinops can range from about 2 to 5 feet tall.
    • Clump-forming: They tend to grow in clumps, expanding outward from their base.

    Leaves:

    • Arrangement: Alternate (arranged singly along the stem)
    • Shape: Deeply lobed or pinnatifid (cut into lobes that extend almost to the midrib), giving them a somewhat thistle-like appearance
    • Texture: Often rough or hairy, sometimes with a silvery or grayish-green color
    • Spines: Many species have spiny margins on their leaves, adding to their defensive character.

    Flowers:

    • Inflorescence: This is where Echinops truly shines! The individual flowers are tiny and tightly packed together into a spherical, globe-like structure. This type of inflorescence is called a capitulum.
    • Color: Most commonly blue, but can also be white, gray-blue, or purplish.
    • Florets: Each tiny flower within the globe is called a floret. They are all tubular in shape.
    • Phyllaries: The globe is surrounded by a series of bracts (modified leaves) called phyllaries, which can be spiny or papery.

    Stems:

    • Sturdy: The stems are generally strong and erect, necessary to support the heavy flower heads.
    • Branching: The degree of branching can vary by species.

    Roots:

    • Taproot: Echinops typically have a deep taproot, which helps them access water in dry conditions. This can make them a bit challenging to transplant.

    Fruits:

    • Achenes: The fruits are dry, one-seeded fruits called achenes. They are often topped with a tuft of hairs (pappus) that aids in wind dispersal.

    Here are some of the characteristics of Echinops, also known as globe thistle:

    • Spiny foliage: The leaves of Echinops are deeply lobed and covered in prickles. This helps to deter herbivores from eating the plant.
    • Spherical flowerheads: The most striking feature of Echinops is its flowers. These are small, individual flowers that cluster together to form a spherical head. The flowerheads come in a variety of colors, including blue, purple, and white.
    • Herbaceous perennial: Echinops is a herbaceous perennial, which means that it dies back to the ground in the winter and then regrows in the spring.
    • Drought tolerant: Echinops is a drought-tolerant plant, which means that it can survive in dry conditions. This makes it a good choice for xeriscapes, which are gardens that are designed to require little or no irrigation.
    • Full sun: Echinops prefers to grow in full sun.
    • Well-drained soil: Echinops needs well-drained soil in order to thrive. Rich soil can cause the plant to flop over.
    • Attracts pollinators: The flowers of Echinops are attractive to bees, butterflies, and other pollinators.

    Echinops is a low-maintenance plant that is easy to care for. It is a valuable addition to any flower garden.

    Echinops exhibit quite a range in height, depending on the species and cultivar. Here is a general overview:  

    Smaller Globe Thistles (around 2-3 feet tall):

    • Echinops ritro (Small Globe Thistle): This commonly grown species usually reaches about 2-3 feet in height. Some cultivars within this species might be even more compact.

    Medium-Sized Globe Thistles (around 3-4 feet tall):

    • Many cultivars of both Echinops ritro and Echinops bannaticus fall within this range.

    Taller Globe Thistles (4 feet and above):

    • Echinops bannaticus (Tall Globe Thistle): As the name implies, this species can reach heights of 4-5 feet or even taller in ideal conditions.
    • Echinops exaltatus (Russian Globe Thistle): This species also tends to be on the taller side, often reaching 4 feet or more.
    • Echinops sphaerocephalus (Big Head Globe Thistle): While the height can vary, this one can also reach 4 feet or more, particularly in rich soils.

    Factors Affecting Height:

    • Species and Cultivar: As mentioned, the inherent genetics of the plant play a significant role in determining its ultimate height.
    • Growing Conditions: Factors like sunlight, soil fertility, and water availability can influence height. Richer soils may lead to taller growth, while poor, dry soils may result in more compact plants.

    Echinops are thankfully quite low-maintenance plants, but a little care goes a long way in ensuring they thrive and provide beautiful displays year after year. Here is a guide to Echinops cultivation:  

    Planting:

    • Timing: Spring or fall is the best time to plant Echinops. This allows them to establish their root systems before the heat of summer or the cold of winter.
    • Location: Choose a sunny spot that receives at least 6 hours of direct sunlight per day.
    • Soil: Echinops prefer well-drained soil. They tolerate a range of soil types but do not do well in heavy clay or consistently wet conditions.
    • Spacing: Space plants about 18-24 inches apart, depending on the mature size of the variety.

    Watering:

    • Establishment: Water regularly during the first growing season to help the plants establish.
    • Mature Plants: Once established, Echinops are quite drought-tolerant. Water occasionally during prolonged dry periods.

    Fertilizing:

    • Generally Not Needed: Echinops do not require frequent fertilization. In fact, too much fertilizer can lead to weak growth and flopping.
    • Poor Soil: If your soil is very poor, you can apply a balanced slow-release fertilizer in spring.

    Maintenance:

    • Deadheading: Deadhead spent flowers to encourage reblooming and prevent self-seeding (if desired).
    • Staking: Taller varieties may need staking to prevent them from flopping over, especially in windy locations.
    • Division: Every 3-4 years, you may need to divide the clumps to maintain their vigor and prevent overcrowding. Divide in spring or fall.
    • Pests and Diseases: Echinops are generally pest and disease-resistant. Occasionally, they may be affected by aphids or powdery mildew. Treat as needed with appropriate organic or chemical controls.

    Winter Care:

    • Leave Standing: Leave the dried flower heads on the plants over winter for added visual interest and habitat for beneficial insects.
    • Mulch: Apply a layer of mulch around the base of the plants in fall to protect the roots from freezing temperatures.

    Propagation:

    • Seed: Echinops can be grown from seed, but it may take a couple of years for plants to reach flowering size.
    • Division: Dividing established clumps is the easiest way to propagate Echinops.

    By following these cultivation tips, you can ensure that your Echinops thrive and provide you with beautiful, globe-shaped blooms for many years to come!

    Echinops, with their striking spherical flower heads and architectural form, can add a unique touch to any garden. Here are some landscaping design tips to help you make the most of these fascinating plants:

    Placement and Combinations:

    • Sunny Borders: Echinops thrive in full sun, so place them in borders that receive at least 6 hours of direct sunlight per day.
    • Cottage Gardens: Their informal charm makes them a perfect fit for cottage gardens, where they can mingle with other flowering perennials.
    • Gravel Gardens and Xeriscapes: Their drought tolerance makes them an excellent choice for gravel gardens and xeriscapes (water-wise gardens).
    • Pollinator Gardens: The flowers are a magnet for bees, butterflies, and other pollinators, so include them in pollinator-friendly plantings.
    • Contrast with Soft Textures: Pair Echinops with plants that have contrasting textures, such as grasses (like Stipa tenuissima or Calamagrostis x acutiflora 'Karl Foerster') or perennials with soft, feathery foliage (like Achillea or Coreopsis).
    • Complementary Colors: Consider the color of the Echinops flowers when choosing companion plants. Blue-flowered varieties look stunning with yellows (like Rudbeckia or Heliopsis), oranges (like Crocosmia), or whites (like Echinacea purpurea 'White Swan').

    Design Ideas:

    • Vertical Accent: Use taller Echinops species (like E. bannaticus) to add vertical accents in the middle or back of borders.
    • Mass Planting: Plant Echinops in groups of three or more to create a bold statement and enhance their visual impact.
    • Rhythm and Repetition: Repeat Echinops throughout the garden to create rhythm and continuity.
    • Edging Plants: Smaller Echinops varieties can be used as edging plants along pathways or borders.
    • Cut Flowers and Dried Arrangements: The flowers are excellent for cutting and drying. Include them in fresh or dried flower arrangements for unique textural interest.

    Practical Considerations:

    • Well-Drained Soil: Ensure the soil is well-drained to prevent root rot.
    • Support for Tall Varieties: Taller varieties may need staking to prevent them from flopping over, especially in windy locations.
    • Deadheading: Deadhead spent flowers to encourage reblooming and prevent self-seeding (if desired).
    • Winter Interest: Leave the dried flower heads on the plants over winter for added visual interest and habitat for beneficial insects.

    Remember to choose Echinops species and cultivars that are appropriate for your climate and growing conditions. With a little planning, you can create a stunning garden that displays the beauty and versatility of these captivating plants.

    There are two main ways to plant Echinops: by seed or by transplanting a young plant. Here is a breakdown for each:

    Planting from Seed:

    • Timing: It is best to sow seeds directly in the garden in autumn. This allows the plant to focus on root growth before winter. Spring planting is also possible but expect less flowering the first year.
    • Location: Choose a spot in your garden that gets full sun and has well-drained soil. Echinops tolerates a wide range of soil types as long as it drains well.
    • Seeding: Sow the seeds directly in the garden to a depth of about one millimeter (1/8 inch) and space them sixty centimeters (2 feet) apart. Keep the soil moist but not soggy until germination, which typically occurs in 14-21 days at a soil temperature of 20-22°C (68-72°F).
    • Care: Young seedlings may need protection from harsh weather or pests until they are established.

    Planting from a Young Plant:

    • Timing: You can plant young Echinops plants any time from fall to spring, as long as the ground is not frozen.
    • Location: Similar to seeds, choose a sunny spot with well-drained soil.
    • Planting: Dig a hole large enough to accommodate the root ball of the young plant. Place the plant in the hole and ensure the top of the root ball sits about an inch below the soil surface. Water the plant well to settle the soil around the roots.
    • Care: Newly planted Echinops will need regular watering during their first season, especially during dry periods. Once established, they are quite drought tolerant.

    Here are some additional tips for planting Echinops:

    • Bare-root plants: If planting bare-root Echinops, soak the roots in water for a few hours before planting.
    • Spacing: Depending on the variety, mature Echinops plants can reach 3-7 feet tall and 1-4 feet wide. Keep this in mind when spacing your plants.
    • Fertilizer: Echinops generally does not require fertilizer, especially in poor soil. Too much fertilizer can encourage floppy growth.

    With a little planning and care, you can enjoy the beautiful and unique flowerheads of Echinops in your garden for many years to come.

    Mass planting Echinops can create a truly stunning visual impact in the landscape. Here is how to make the most of this technique:

    Choosing the Right Echinops:

    • Consider Size and Habit: For mass planting, it is often best to choose species or cultivars with a consistent size and growth habit. This will create a more unified and cohesive look.
      • Echinops ritro and its cultivars are good choices for smaller areas, while E. bannaticus works well in larger spaces.
    • Color Harmony: Decide on a color scheme. Do you want a sea of blue globes, a drift of white, or perhaps a mix of blue and white varieties for contrast?

    Planting Design and Spacing:

    • Odd Numbers: Planting in odd numbers (3, 5, 7, etc.) tends to be more visually appealing than even numbers.
    • Spacing: Space the plants about 18-24 inches apart. This allows for adequate air circulation and prevents overcrowding while still achieving a massed effect.
    • Drift or Block: Plant in a large drift or block to create a bold statement. This works particularly well in informal or naturalistic settings.
    • Edge a Border: Use a mass planting of Echinops to define the edge of a border or pathway.
    • Combine with Other Plants: While mass planting can be striking on its own, consider combining Echinops with other perennials for added interest. Grasses, yarrow (Achillea), and sedums are good companions.

    Location and Conditions:

    • Full Sun: Echinops need plenty of sunlight to thrive, so choose a location that receives at least 6 hours of direct sun per day.
    • Well-Drained Soil: Good drainage is essential to prevent root rot. Amend heavy clay soil with organic matter to improve drainage.

    Care and Maintenance:

    • Watering: Water regularly during the first growing season to help the plants establish. Once established, Echinops are quite drought-tolerant.
    • Deadheading: Deadhead spent flowers to encourage more blooms and prevent self-seeding (if desired).
    • Staking: Taller varieties may need staking, especially in windy locations.
    • Division: Every few years, you may need to divide the clumps to maintain their vigor and prevent overcrowding.

    Examples of Mass Planting Combinations:

    • Echinops ritro 'Veitch's Blue' massed with Calamagrostis x acutiflora 'Karl Foerster' (Feather Reed Grass) for a striking contrast of blue and feathery gold.
    • Echinops sphaerocephalus planted in a large drift with Achillea 'Moonshine' (yarrow) for a soft, romantic look in shades of white and yellow.
    • Echinops bannaticus 'Taplow Blue' combined with Sedum 'Autumn Joy' for late-season color and textural interest.

    With careful planning and the right combination of plants, a mass planting of Echinops can be a truly show-stopping feature in your landscape!

    There are many varieties of Echinops, but some of the most popular ones include:

    • Echinops ritro (Globe Thistle): This is the most common type of Echinops. It has steel-blue flowers and grows to about 3-4 feet tall.
    • Echinops bannaticus (Tall Globe Thistle): This variety is taller than Echinops ritro, growing up to 6-7 feet tall. It has silvery-blue flowers.
    • Echinops sphaerocephalus (Big Head Globe Thistle): This variety has the largest flowerheads of all the Echinops, up to four inches in diameter. The flowers are a pale lavender-blue color.
    • Echinops veneta (White Globe Thistle): This variety is unique in that it has white flowers. It grows to about 3-4 feet tall.
    • Echinops ritro 'Veitch's Blue': This is a popular cultivar of Echinops ritro with particularly vibrant blue flowers.
    • Echinops bannaticus 'Blue Glow': This cultivar of Echinops bannaticus is known for its intense blue flowerheads.

    Here is how to care for Echinops in your garden:

    Watering:

    • Newly planted: Water your Echinops regularly during its first growing season, especially during dry periods. Aim for the soil to be consistently moist but not soggy.
    • Established plants: Echinops are drought tolerant once established. You generally will not need to water them unless there is a prolonged dry spell.

    Sunlight:

    • Plant your Echinops in a location that receives full sun. This will encourage good flowering.

    Soil:

    • Echinops can tolerate a wide range of soil types as long as it drains well. They actually prefer poor to moderately fertile soil. Rich soil can cause the stems to become weak and floppy.
    • If your soil is heavy clay, consider amending it with sand or gravel to improve drainage.

    Fertilizing:

    • Generally, Echinops do not require fertilizing, especially in poor soil. Too much fertilizer can lead to weak, floppy growth and reduce flowering.

    Deadheading:

    • Deadheading is optional, but it can help to encourage continued flowering throughout the season. Simply remove spent flowerheads once the blooms fade. You can also leave the flowerheads on the plant for winter interest.

    Winter Care:

    • Echinops are hardy perennials and can withstand cold winters. They do not require any special winter protection. However, in areas with very cold winters or poor drainage, you can mulch around the base of the plant with a light layer of organic matter, such as shredded leaves or compost.

    Other Care:

    • Established Echinops typically do not need staking. However, for some of the taller varieties, or if the flowerheads are particularly large and heavy, staking may be necessary to prevent the stems from flopping over.
    • Every few years, you may want to divide your Echinops clumps to maintain vigor and prevent overcrowding.

    By following these simple care tips, your Echinops will thrive and add beauty to your garden for many years to come.

    Here is a comprehensive calendar of care for Echinops, detailing the key maintenance tasks throughout the year:

    Spring:

    • Planting: Plant Echinops in spring after the last frost.
    • Division: Divide established clumps in spring if needed.

    Summer:

    • Watering: Water regularly during the first growing season to establish new plants. Once established, Echinops are drought-tolerant. Water only occasionally during prolonged dry spells.
    • Deadheading: Remove spent blooms to encourage continuous flowering and prevent self-seeding.
    • Staking: Taller varieties may need staking for support, especially in windy conditions.

    Fall:

    • Mulching: Apply a layer of mulch around the base of the plants to protect them from winter temperatures.
    • Prepare for Winter: In colder climates, cut back the stems to ground level before winter.

    Winter:

    • Dormant: Echinops are dormant during winter. They lose their leaves and go into a resting phase.

    Additional Tips:

    • Fertilization: Echinops are generally low-maintenance and do not require much fertilizer. If your soil is poor, apply a balanced slow-release fertilizer in spring.
    • Pests and Diseases: Echinops are generally pest and disease-resistant. Monitor for aphids or powdery mildew and treat as needed.

    By following this calendar, you can ensure that your Echinops thrive and provide you with a long-lasting, low-maintenance display of beauty in your garden.

    Yes, Echinops, also known as globe thistle, are absolutely fantastic at attracting pollinators! Their flowers are a magnet for bees, butterflies, and other beneficial insects. Here is why:

    • Abundant nectar: The individual florets that make up the spherical Echinops flowerhead produce a good amount of nectar, a sweet reward that pollinators seek out for energy.
    • Color: The most common varieties of Echinops boast vibrant blue or white flowerheads, colors that are well-known to attract pollinators.
    • Flower structure: The densely packed florets create a landing platform for pollinators to easily access the nectar.

    By attracting pollinators to your garden, Echinops helps to ensure the reproduction of other flowering plants as well. So not only are they beautiful additions to your garden, but they also play an important role in the local ecosystem.

    The good news is that Echinops are generally considered to be relatively pest and disease resistant! However, there are a couple of minor issues to keep an eye out for:

    • Aphids: These are the most common pests that might bother your Echinops. Aphids are small, soft-bodied insects that suck sap from the leaves. They typically appear in spring or early summer and can cause leaves to curl or become distorted. In most cases, an infestation will not be severe enough to harm the plant. If the infestation is significant, you can try spraying the aphids off with water or using insecticidal soap.
    • Echinops leaf miner: This is a small fly whose larvae tunnel within the leaves of Echinops. The damage usually appears as whitish brown, discolored blotches on the leaves. Similar to aphids, this issue rarely requires intervention as the plant will tolerate the damage and still flower.
    • Powdery mildew: This fungal disease can occur in damp conditions, especially if there's poor air circulation around the plant. It appears as white powdery spots on the leaves. While not a major threat, you can improve air circulation by thinning overcrowded plantings. In severe cases, you can use a fungicide specifically labeled for powdery mildew on ornamentals.

    Overall, Echinops are low-maintenance plants that are unlikely to be significantly bothered by pests or diseases. With proper planting and care, you can enjoy these beautiful perennials in your garden for many years to come.

    Absolutely, Echinops, also known as globe thistle, can be a fantastic addition to floral arrangements! Here is why they are a great choice:

    • Unique Textural Element: The spiky foliage and spherical flowerheads of Echinops add a touch of drama and interest to arrangements. They provide wonderful contrast with softer flowers and greenery.
    • Versatility: Echinops come in a variety of colors, most commonly blue and white, but also purple and lavender. This allows you to incorporate them into arrangements with a wide range of color palettes.
    • Fresh or Dried: Echinops can be used in fresh or dried arrangements. Freshly cut Echinops add a vibrant pop of color, while dried Echinops retain their interesting shape and texture for long-lasting arrangements.

    Here are some things to consider when using Echinops in floral arrangements:

    • Fresh Echinops: Since the stems can be somewhat thick and prickly, it is recommended to use a sharp knife or floral shears to cut them. You may also want to wear gloves when handling them to avoid getting pricked.
    • Dried Echinops: Dried Echinops are a popular choice for long-lasting arrangements. They tend to be a more muted shade of their original color, but they still add a wonderful textural element.

    Overall, Echinops are a versatile and interesting flower choice for both fresh and dried arrangements. Their unique appearance and ease of care make them a valuable addition to any florist's toolkit.

    No, Echinops are generally not considered invasive. While they can self-seed readily, they typically do not spread aggressively and are unlikely to take over your garden or natural areas.

    Here is a breakdown of why Echinops are not typically invasive:

    • Limited seed dispersal: Unlike some invasive plants, Echinops does not have specialized mechanisms for spreading its seeds long distances. They primarily rely on gravity for seed dispersal, meaning the seedlings will likely grow up near the parent plant.
    • Non-aggressive growth: Echinops tend to form clumps and do not send out runners or underground stems that can quickly colonize new areas.
    • Easy control: Even if Echinops self-seeds somewhat, it is easy to control by deadheading the flowers before they go to seed. Simply remove the spent flowerheads before they develop fluffy seed heads.

    However, it is always a good idea to be aware of the potential for any plant to spread in unexpected ways. If you are concerned about Echinops spreading in your garden, deadheading is a simple and effective way to prevent unwanted seedlings.

    There are two main methods for propagating Echinops, and each has its own ideal timing:

    • Dividing established clumps: This is best done in early spring or fall when the plant is dormant. During this time, the plant is not actively using its energy for growth, so it will be less stressed by the division process.
    • Propagating from root cuttings: This method is best done in late winter or early spring. Again, this coincides with the dormant period when the plant is better equipped to handle the stress of root disturbance.

    There are several benefits to planting Echinops in your garden, both aesthetic and practical:

    • Unique and beautiful blooms: Echinops boast stunning spherical flowerheads in shades of blue, white, purple, and lavender. These add a touch of drama and architectural interest to your garden, especially when planted in borders or beds.
    • Low-maintenance: Echinops are generally easy to care for. They are drought tolerant once established, and do not require frequent watering or fertilizing.
    • Deer and rabbit resistant: The spiny foliage of Echinops deters deer and rabbits from munching on the plant, making it a great choice for areas where these pests are a problem.
    • Attracts pollinators: The nectar-rich flowers of Echinops are a magnet for bees, butterflies, and other beneficial insects. This helps to promote pollination in your garden and supports the local ecosystem.
    • Versatility: Echinops come in various heights and colors, making them suitable for a variety of garden styles. They can be incorporated into cottage gardens, wildflower meadows, xeriscapes, or even rock gardens.

    Echinops Species, Groups and Cultivars

    The diversity within the Echinops genus can be a bit tricky to navigate because there are so many species and some overlap in how they are grouped. Here is a breakdown to help you understand the variety:

    Species:

    As mentioned before, there are over 130 recognized Echinops species. Here are a few of the most commonly found in gardens:

    • Echinops ritro (Small Globe Thistle): This is probably what comes to mind when most people think "globe thistle." It has intense steel-blue flowers and a more compact growth habit than some other species.
      • Cultivars of Echinops ritro: 'Veitch's Blue' (deep blue flowers), 'Platinum Blue' (silvery-blue flowers)
    • Echinops bannaticus (Tall Globe Thistle): As the name suggests, this one gets quite tall! It has silvery-blue flowers and is a popular choice for the back of borders.
      • Cultivars of Echinops bannaticus: 'Taplow Blue' (large, deep blue flowers), 'Blue Glow' (intense blue flowers)
    • Echinops sphaerocephalus (Big Head Globe Thistle): This species has larger, rounded flower heads that are often white or a very pale gray-blue.
    • Echinops exaltatus (Russian Globe Thistle): Similar to E. sphaerocephalus with large flower heads but tends to have a taller growth habit.

    Informal Groupings:

    Sometimes you will see globe thistles described in broader terms, though these are not formal taxonomic groups:

    • Blue Globe Thistles: This generally refers to species and cultivars with blue flowers, like E. ritro, E. bannaticus, and their cultivars.
    • White Globe Thistles: This usually indicates species like E. sphaerocephalus and E. exaltatus, which have white or very pale flower heads.

    Cultivars:

    Cultivars are bred for specific traits like flower color, size, or growth habit. They are usually indicated by a name in single quotes following the species name (e.g., Echinops ritro 'Veitch's Blue').

    Important Note: There can be natural variation within a species, and sometimes the lines between species can be a bit blurry. This is part of what makes globe thistles so interesting!
