    Big Impact, Flowering Groundcover

    • Charming, Miniature Blooms: Enjoy a carpet of tiny, snapdragon-like flowers in shades of purple-blue, lavender, or white (depending on the cultivar) throughout spring and early summer.
    • Incredibly Low-Maintenance: This groundcover is a breeze to care for, requiring minimal watering, fertilizing, or mowing once established. It is perfect for busy gardeners or those with challenging growing conditions.
    • Tough and Durable: Mazus reptans is surprisingly resilient. It can tolerate light foot traffic, making it suitable for pathways, between steppingstones, or as a small-scale lawn substitute.
    • Fast-Spreading Coverage: Quickly fill in bare spots and create a dense, weed-suppressing mat. It spreads readily by creeping stems that root at the nodes.
    • Versatile Groundcover Solution: Ideal for a variety of landscape applications, including rock gardens, borders, edging, containers, and even as a living mulch around shrubs and trees.
    • Adaptable to Sun and Shade: Thrives in full sun to partial shade, giving you flexibility in placement. (Note: Flowering will be most profuse in full sun.)
    • Attracts Pollinators: The small flowers are attractive to bees and other beneficial insects.
    • Deer Resistant: Deer tend not to bother this groundcover.

    Site Selection:

    • Light: Full sun (at least 6 hours of direct sunlight per day) to partial shade. Best flowering occurs in full sun. In hotter climates (zones 8-9), some afternoon shade is beneficial.
    • Soil: Prefers moist, well-drained soil rich in organic matter. However, it is adaptable to a range of soil types, including sandy and clay soils, as long as drainage is adequate. Avoid constantly soggy conditions, which can lead to root rot. A slightly acidic to neutral pH (6.0-7.0) is ideal.
    • Hardiness Zones: It is hardy in USDA zones 5 to 8.

    Planting:

    • Timing: Spring or early fall is the best time to plant.
    • Spacing: Space plants 6-12 inches apart. Closer spacing will result in faster coverage.
    • Depth: Plant at the same depth as the plant was growing in its container. The crown of the plant (where the stems meet the roots) should be level with the soil surface.
    • Preparation: Dig a hole that is slightly wider and as deep as the root ball.
    • Planting: Gently remove the plant from its container and place it in the hole.
    • Backfill and Water: Fill the hole with soil, gently firming it around the roots. Water thoroughly after planting.

    Watering and Care:

    • Watering: Water regularly, especially during the first growing season, to establish a strong root system. Once established, Mazus reptans is relatively drought-tolerant but benefits from occasional watering during dry periods. Aim to keep the soil consistently moist, but not soggy.
    • Mulching: Apply a thin layer of organic mulch (shredded bark, compost) around the plants to help retain moisture, suppress weeds, and regulate soil temperature. Keep the mulch away from the crown of the plant.
    • Fertilizing: Generally, not necessary. If growth is slow or foliage is pale, you can apply a light application of a balanced, slow-release fertilizer in early spring. Avoid over-fertilizing, which can lead to excessive growth and reduced flowering.
    • Weeding: Maintain a weed-free environment, particularly while plants are becoming established.

    Pruning and Maintenance:

    • Mowing (Optional): If used as a lawn alternative, Mazus reptans can be mowed occasionally on a high setting to maintain a neat appearance. However, mowing is not required.
    • Shearing (Optional): After flowering, you can shear back the plants lightly to encourage bushier growth and potentially a second flush of blooms. This is not essential.
    • Division (Optional): To propagate or rejuvenate older plants, divide them in spring or early fall. Dig up the clumps and carefully separate them into smaller sections, ensuring each section has roots and shoots. Replant immediately.

    Propagation:

    • Division: The easiest and most common method. Divide plants in spring or fall.
    • Stem Cuttings: Take stem cuttings in spring or early summer. Root them in a moist potting mix or perlite.
    • Seeds: Mazus reptans can be grown from seed, but germination can be erratic. Sow seeds indoors in late winter or early spring.

    Potential Problems:

    • Slugs and snails: These pests can sometimes be a problem, especially in moist, shady conditions. Use organic slug and snail control methods if necessary.
    • Root Rot If the soil does not have good drainage, and remains too wet, root rot can occur.

    Dendranthema 'Sheffield Pink' ( Chrysanthemum 'Sheffield Pink'):

    • Late-Season Color:  It provides a beautiful display of soft, apricot-pink, daisy-like flowers with golden-yellow centers in late summer and fall, extending the garden's color palette.
    • Hardiness and Vigor: This is considered a hardy and vigorous variety, making it relatively dependable.
    • Attracts Pollinators: The flowers attract butterflies, contributing to a healthy garden ecosystem.
    • Versatility: It is suitable for various garden applications, including borders, mass plantings, rock gardens, and containers.
    • Cut Flowers: It is suitable for cut flower arrangements.
    • Deer Resistant: It has moderate deer resistance.
    • Sunlight: Prefers full sun but can tolerate light shade.
    • Soil: Requires well-drained, fertile soil.
    • Watering: Needs consistent moisture, especially during the growing season.
    • Planting: Spring or fall are ideal planting times.
    • Pinching: inching back stems in late spring to mid-summer encourages bushier growth and more blooms.
    • Maintenance:
      • Deadheading spent flowers can prolong blooming.
      • Cut back plants after flowering.
      • Mulching in colder climates provides winter protection.
      • Divide plants every 2-3 years.
    • Potential Problems: Watch for pests like aphids, thrips, and spider mites.
      • Be aware of potential diseases such as Botrytis, leaf spots, and powdery mildew.
    • Hardiness Zones: Generally, thrives in USDA hardiness zones 5-9.

    The terms "Dendranthema" and "Chrysanthemum" can be a bit confusing, as they refer to the same group of plants but have been used differently over time. Here is a quick rundown:

    1. Historical Naming: The genus Chrysanthemum was originally used to classify these plants. However, in 1961, the genus was split into several different genera, and many species were reclassified under the name Dendranthema.
    2. Reclassification: More recently, the genus Chrysanthemum has been reinstated, and many of the plants that were moved to Dendranthema have been moved back to Chrysanthemum.
    3. Common Names: Despite the botanical changes, many gardeners and horticulturists still use the name Chrysanthemum, especially when referring to popular garden varieties like the hardy mums.

    So, whether Dendranthema or Chrysanthemum, you are talking about the same beautiful, versatile plants that brighten up gardens and floral arrangements alike!

    Compare Selected

    Dendranthema is a genus of flowering plants that includes chrysanthemums, also known as garden mums. They are popular for their vibrant fall blooms and are widely cultivated in gardens and used as cut flowers.

    Originally, chrysanthemums were classified under the genus Chrysanthemum. However, in 1961, botanists reclassified the hardy garden mums into the genus Dendranthema. This reclassification aimed to distinguish them from the less hardy florist's chrysanthemums, which retained the Chrysanthemum classification.

    Dendranthema plants are typically hardy perennials that thrive in full sun to partial shade and well-drained soil. They come in a variety of colors, excluding blue, and bloom in various forms, from single to fully double flowers.

    Dendranthema plants are relatively low-maintenance and can tolerate a range of soil conditions. They require moderate watering and are generally resistant to pests and diseases.

    Overall, Dendranthema plants are a beautiful and resilient addition to any garden, providing vibrant fall color and requiring minimal care.

    • Plant Type: Perennial.
    • Growing Zones: Zones 5 to 9.
    • Height and Width: 12 inches tall and 18 inches wide.
    • Foliage: Aromatic, somewhat fleshy leaves that are lobed in a palmate fashion.
    • Flowers: Daisylike flower heads with white, yellow, pink, or purple petals, blooming in mid- to late summer and fall.
    • Planting Location: Full to half sun, in rich, moist, well-drained soil. Sandy soil is ideal.
    • Watering and Feeding: Average water; feed with an all-purpose organic fertilizer in spring.
    • Care: Pinch several times between midspring and midsummer for bushy, later-blooming plants. Divide plants every 2 years in spring.

    Chrysanthemums, often affectionately called "mums," are a staple in gardens, bringing vibrant bursts of color as summer transitions to fall. Native to East Asia and northeastern Europe, these beloved plants have a rich history in gardens around the world. But did you know that the mums you see gracing gardens in autumn are actually part of the Dendranthema genus? This article delves into the world of chrysanthemums and Dendranthema, providing valuable insights for gardeners of all levels.

    Common Names

    Chrysanthemum is a genus of herbaceous perennials in the aster family (Asteraceae). These plants are known by a variety of common names, including:

    • Mum
    • Chinese Mum
    • Daisy Mum
    • Florist's Mum
    • Cushion Mum
    • Spoon Mum
    • Fuji Mum
    • Spider Mum
    • Football Mum

    While Dendranthema are commonly referred to as chrysanthemums or garden mums. Interestingly, the classification of these plants has shifted over the years. Originally classified as Chrysanthemum, they were later separated into several genera, including Dendranthema in 1961. The scientific name for garden mums is Dendranthema x grandiflora. However, many gardeners and horticulturists still use the name Chrysanthemum, especially when referring to popular garden varieties.

    Chrysanthemum and Dendranthema Varieties

    Chrysanthemums and Dendranthema come in a dazzling array of shapes, sizes, and colors. Here is a table summarizing the different varieties:

    Growth Requirements Chrysanthemums and Dendranthema are relatively easy to grow, but understanding their basic needs is crucial for their success.

    • Soil and Sunlight Both Chrysanthemums and Dendranthema thrive in fertile, well-drained soil. Loamy or sandy soil is ideal, while heavy clay can be problematic. Incorporating organic matter, such as compost or peat moss, can improve drainage and provide essential nutrients. Chrysanthemums are heavy feeders and benefit from aged manure or compost added to the soil. While they generally prefer full sun (at least six hours of direct sunlight per day), Dendranthema can tolerate part shade/part sun, especially in hot climates.
    • Water Needs While these plants need regular watering, especially during the growing season, it is important to avoid overwatering. Allow the soil to dry out slightly between waterings to prevent root rot.
    • Fertilizer Mums are pretty tough and can thrive on their own, but they benefit from light and frequent feedings with a balanced fertilizer during the growing season.
    • Hardiness Zones Most garden mums (Chrysanthemum x morifolium) are hardy in USDA Zones 5 to 9. However, some varieties can tolerate colder winters, even down to Zone 3. Dendranthema also exhibit a similar hardiness range, with some varieties thriving in Zones 5 to 9 and others extending to Zone 3. The key to successful overwintering of garden mums, especially in colder zones, lies in proper planting and care.

    Bloom Times

    Chrysanthemums and Dendranthema are typically known for their fall blooms, with colors ranging from shades of yellow, orange, red, purple, bronze, pink, or white. However, the exact bloom time can vary depending on the variety and climate. Early-blooming cultivars may start flowering in mid-summer, while late-blooming varieties can continue to display their vibrant colors well into autumn.

    Interestingly, the bloom times of chrysanthemums can be manipulated by controlling daylight exposure. Growers often force them to flower at specific times by exposing them to shorter daylight periods and longer dark periods. This explains why you can find blooming mums at any time of year.

    To encourage more blooms, a technique called "pinching" is often used. This involves removing the early season growth to promote branching and the formation of more stems, ultimately leading to more flowers.

    Pests and Diseases

    While generally resilient, chrysanthemums and Dendranthema can be susceptible to certain pests and diseases. Fungal diseases are more prevalent than insect pests.

    Pests

    Overwintering Tips

    In colder climates, chrysanthemums and Dendranthema may require some extra care to survive the winter. Here are some tips for overwintering these plants:

    • Mulch: Apply a thick layer of mulch, such as straw or pine needles, around the base of the plant to insulate the roots and prevent frost heaving.
    • Water: Continue watering until the first hard frost, then gradually reduce watering as winter approaches.
    • Protect from Wind: If possible, plant mums in a sheltered location to protect them from harsh winter winds.
    • Container Plants: For containerized mums, consider moving them to a protected location, such as an unheated garage or a cold frame. You can also force the plant into dormancy by cutting back the top and storing it in a cool (40-45°F) location like a basement or insulated garage.

    The timing of planting mums is crucial for their winter survival, as early planting allows for better root establishment. It is also recommended to divide mums every other year to maintain their vigor and bloom production.

    Propagation Tips

    Chrysanthemums and Dendranthema can be propagated through various methods, including cuttings and division.

    Cuttings

    To propagate from cuttings:

    1. Take 4-6 inch cuttings from healthy, non-flowering stems.
    2. Remove the lower leaves and dip the cut end in rooting hormone.
    3. Plant the cuttings in a well-draining potting mix.
    4. Keep the soil consistently moist but not waterlogged.
    5. Place the cuttings in indirect sunlight.

    Division

    To propagate by division:

    1. Wait until spring when new growth appears.
    2. Dig up the entire plant clump.
    3. Cut out the old central portion of the clump and discard it.
    4. Divide the remaining portion into sections, ensuring each section has roots and shoots.
    5. Replant the divisions in the desired location.

    Dividing chrysanthemums not only creates new plants but also helps to rejuvenate older clumps and improve their vigor.

    Uses

    Chrysanthemums are versatile plants with various uses in the garden and beyond. They are commonly used for:

    • Borders: Their vibrant colors and varied forms make them excellent border plants.
    • Containers: They thrive in containers, adding a touch of fall color to patios and balconies.
    • Foundations: They can be used to soften the foundation of a house.
    • Massing: Planting them in masses creates a dramatic display of color.
    • Specimens: Some varieties are striking enough to be used as specimen plants.

    Chrysanthemums are also popular cut flowers. To ensure they last longer after harvest, they are often grown at high relative humidity.

    Chrysanthemums and Dendranthema are versatile and rewarding plants that can bring a vibrant touch to any garden. While the names may be used interchangeably, understanding the distinction between Chrysanthemum and Dendranthema can provide valuable context for their history and classification. These plants thrive in fertile, well-drained soil with ample sunlight and require consistent moisture without overwatering.

    Remember that timing is crucial. Plant mums early to allow for proper root establishment before winter and divide them every other year to maintain their vigor. When it comes to propagation, both cuttings and division are effective methods.

    While generally resilient, be mindful of potential pests and diseases, particularly fungal issues. By understanding their specific needs and providing proper care, armed with this knowledge, you can cultivate thriving chrysanthemums and Dendranthema in your garden for years to come.

    Chrysanthemum and Dendranthema FAQ

    It is a bit of a winding story, so buckle up:

    1. The Early Days (Pre-1753):

    • Chrysanthemums were cultivated in China for centuries, even millennia, before formal botanical naming.
    • They were introduced to Japan around the 8th century and became highly significant culturally.
    • Europeans encountered them in the 17th century, with the first known European illustration appearing in 1689.

    2. Linnaeus Enters the Scene (1753):

    • Carl Linnaeus, the father of modern taxonomy, established the genus Chrysanthemum in his landmark work, Species Plantarum.
    • He included several species, but the one that defined the genus (the "type species") was the corn marigold (Chrysanthemum coronarium), a European annual.

    3. The Split (Mid-20th Century):

    • Botanists realized that the widely cultivated garden chrysanthemums, mostly derived from East Asian species, were quite distinct from the corn marigold.
    • In 1961, Russian botanist Nikolai Tzvelev moved these garden mums to a new genus: Dendranthema. This was based on differences in flower structure and chromosome number.
    • This split was controversial, and not universally adopted.

    4. Confusion Reigns:

    • For several decades, there was inconsistency in how these plants were named. Some botanists and horticulturalists used Chrysanthemum, others used Dendranthema.
    • The Dutch, major players in the flower trade, largely adopted Dendranthema, adding to the confusion.

    5. Reunification (1999):

    • To resolve the issue, a proposal was submitted to the International Botanical Congress (IBC), the body governing plant names.
    • The proposal suggested changing the type species of Chrysanthemum from the corn marigold to, an East Asian species closely related to the garden mums.
    • The IBC accepted this in 1999. This meant all those garden chrysanthemums were officially back in the Chrysanthemum Chrysanthemum indicum genus, and Dendranthema became a synonym.

    Why the Change Back?

    • Stability: It ended the confusion and provided a single, universally accepted name.
    • Practicality: Chrysanthemum was already the widely used name in most of the world.
    • Reflecting Relationships: It better aligned the genus name with the most commonly cultivated and economically important chrysanthemums.

    So, while Dendranthema was valid for a time, it is now outdated. But understanding this history helps us appreciate the complexities of plant classification and how scientific knowledge evolves!

    So, Dendranthema is now considered outdated and synonymous with Chrysanthemum.

    This is where things get a little tricky because of the naming history!

    The most accurate scientific name for what was once called Dendranthema is now simply Chrysanthemum.

    Here is why:

    • Historically: Dendranthema was a separate genus created in the mid-20th century to classify the hardy garden mums.
    • Modern Botany: In 1999, botanists decided to merge Dendranthema back into the broader Chrysanthemum genus.

    So, while you might still find older sources using Dendranthema, the current and accepted scientific name is Chrysanthemum.

    Think of it like a family reunion: The garden mums (formerly Dendranthema) were separated from the rest of the Chrysanthemum family for a while, but they have all been brought back together under the same family name.

    Here is an overview of chrysanthemums morphology, keeping in mind that the term Dendranthema is no longer used:

    General Morphology of Chrysanthemum

    • Habit: Most chrysanthemums are herbaceous perennials, meaning they have non-woody stems and die back to the ground in winter, re-emerging in spring. Some species can be slightly woody subshrubs.
    • Roots: They typically have fibrous root systems. Some species may also spread by rhizomes (underground stems).
    • Stems: The stems are usually erect and branched.
    • Leaves:
      • Arrangement: Leaves are arranged alternately along the stems.
      • Shape: Leaf shapes vary, but they are often lobed, pinnatifid (deeply cut), or toothed.
      • Surface: Leaves are often somewhat fleshy and may have a slightly hairy texture.
      • Aroma: Many chrysanthemums have aromatic leaves, which release a distinctive scent when crushed.

    Flowers (Inflorescences):

    • Composite Flower Heads: What we perceive as a single chrysanthemum flower is actually a composite inflorescence made up of many tiny individual flowers called florets.
      • Disc Florets: These are the small, tubular florets in the center of the flower head. They are usually yellow.
      • Ray Florets: These are the petal-like structures that surround the disc florets. They come in a wide variety of colors, including white, yellow, pink, red, purple, orange, and bronze.
    • Flower Head Shapes: Chrysanthemum flower heads exhibit a remarkable diversity of forms, including:
      • Single: Daisy-like with a single row of ray florets.
      • Semi-double: Similar to single but with more than one row of ray florets.
      • Double: Fully double with many rows of ray florets, often obscuring the disc florets.
      • Anemone: A raised center of disc florets surrounded by a ring of flat ray florets.
      • Pompon: Small, round, button-like.
      • Spider: Long, tubular ray florets that resemble spider legs.
      • Spoon: Ray florets with a spoon-like shape.
      • Quill: Straight, tubular ray florets.
    • Bloom Time: Chrysanthemums typically bloom in late summer and fall, though some cultivars are bred to bloom earlier.

    Fruit:

    • Achenes: Chrysanthemums produce dry, one-seeded fruits called achenes. These are similar to sunflower seeds.

    Variations:

    • Size: Chrysanthemums range in size from compact dwarf varieties to taller, bushier types.
    • Color: The color of the ray florets is incredibly diverse, with almost every color except blue represented.
    • Fragrance: Some chrysanthemums have a strong fragrance, while others are nearly scentless.

    Grow some chrysanthemums? Excellent choice. They are rewarding plants that bring a burst of color to the fall garden. Here is a guide to their cultivation, keeping in mind that "Dendranthema" is outdated:

    Planting

    • Timing: Plant in spring or early fall, giving them time to establish before summer heat or winter cold.
    • Location: Choose a sunny spot that receives at least 6 hours of direct sunlight per day. Some afternoon shade is beneficial in hot climates.
    • Soil: Chrysanthemums thrive in well-drained soil that is rich in organic matter. Amend heavy clay soil with compost or other organic matter to improve drainage.
    • Spacing: Space plants 1 to 2 feet apart, depending on the mature size of the cultivar.

    Watering

    • Regular Watering: Water regularly, especially during dry periods, to keep the soil consistently moist but not soggy.
    • Avoid Overhead Watering: Water at the base of the plants to prevent fungal diseases.

    Fertilizing

    • Feed Regularly: Chrysanthemums are heavy feeders. Fertilize with a balanced, slow-release fertilizer in spring and mid-summer.
    • Foliar Feeding: You can also supplement with a liquid fertilizer every few weeks.

    Pinching

    • Encourage Bushy Growth: Pinch back the tips of the stems when they reach about 6 inches tall. Repeat every few weeks until mid-summer. This encourages bushier growth and more flowers.

    Deadheading

    • Prolong Blooming: Remove faded flowers regularly to encourage the plant to produce more blooms and extend the flowering season.

    Supporting

    • Stake Tall Varieties: Taller chrysanthemum varieties may need staking to prevent them from flopping over.

    Dividing

    • Maintain Vigor: Divide chrysanthemum clumps every 2-3 years in spring to maintain plant vigor and prevent overcrowding.

    Overwintering

    • Mulch in Cold Climates: In colder climates (zones 5-6), protect chrysanthemums over winter by mulching around the base of the plants after the first frost.
    • Cut Back in Spring: Cut back the dead stems in early spring before new growth emerges.

    Pests and Diseases

    • Common Pests: Chrysanthemums can be susceptible to aphids, spider mites, leaf miners, and other pests. Monitor plants regularly and treat infestations promptly.
    • Potential Diseases: Keep an eye out for fungal diseases like powdery mildew and leaf spot. Ensure good air circulation and avoid overhead watering to prevent these issues.

    Tips for Success

    • Choose the Right Cultivars: Select chrysanthemum varieties that are suited to your climate and growing conditions.
    • Provide Good Drainage: Ensure the soil drains well to prevent root rot.
    • Do not Overcrowd: Give plants enough space to grow and breathe.
    • Protect from Frost: In colder areas, protect plants from early frosts.

    With proper care, your chrysanthemums will reward you with a spectacular display of fall color! Let me know if you have any other questions. Happy gardening!

    You are thinking about how to best use chrysanthemums in your garden! They are such versatile plants. Here are some design tips to get you started, keeping in mind that "Dendranthema" is outdated:

    Interesting Fact:

    Chrysanthemum indicum played a pivotal role in the resolution of the Chrysanthemum/Dendranthema naming debate. When botanists decided to merge the two genera, they chose C. indicum as the new "type species" for Chrysanthemum. This solidified the classification of garden mums within the Chrysanthemum genus.

    Here are some interesting facts about Chrysanthemum x morifolium, also known as the Autumn Mum:

    1. Name Origin: The name "Chrysanthemum" comes from the Greek words "chrysos" (gold) and "anthemon" (flower), reflecting the plant's golden blooms.
    2. Flower Variety: These flowers come in a wide range of colors, from brownish shades to pastels and vibrant yellows. They can be solid, bi-color, or edged with another color.
    3. Edible Flowers: The petals and flower buds are used to make a sweet drink in Asia and a wine in Korea.
    4. Butterfly Magnet: The flowers attract butterflies, making them a great addition to a pollinator garden.
    5. Growth Habit: Autumn mums form erect mounds that can reach 1 to 3 feet tall and 1 to 2 feet wide.
    6. Maintenance Tip: To encourage bushy, compact growth, cut them back three times during the spring and summer, with the last cut around August 15th.
