    • Asarum

    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.

    • Thrives in Woodland Conditions: Naturally adapted to woodland environments, Asarum splendens flourishes in moist, shady conditions, making it a perfect choice for woodland gardens, shady borders, and beneath trees.
    • Light: Prefers partial shade to full shade. Asarum splendens needs shade to thrive and display its best foliage color. Avoid direct sunlight, which can scorch the leaves and fade the vibrant patterns. Deep shade is well-tolerated.
    • Soil: Plant in moist, fertile, humus-rich, well-drained soil. Mimic its native woodland environment. Amend heavy clay or sandy soils generously with compost, leaf mold, or other organic matter to improve moisture retention, drainage, and fertility. Slightly acidic to neutral soil pH is ideal.
    • Planting Time: Spring or fall are the best times to plant Asarum splendens. Avoid planting during the heat of summer or when the ground is frozen.

    Planting Instructions:

    1. Choose Your Location: Select a fully shaded to partially shaded location with moist, well-drained, humus-rich soil.
    2. Prepare the Planting Hole: Dig a hole that is twice as wide as the root ball and just as deep.
    3. Amend the Soil (Crucial): Generously amend the backfill soil with compost, leaf mold, or other organic matter. Asarum splendens thrives in rich, woodland-type soil.
    4. Remove from Container: Gently remove the Asarum splendens from its container, loosening any circling roots if present.
    5. Planting Depth: Place the root ball in the center of the hole, ensuring the top of the root ball is level with the surrounding soil. Avoid planting too deeply; the crown should be at soil level.
    6. Backfill and Firm: Backfill the hole with the prepared soil mixture, gently firming around the base of the plant.
    7. Water Thoroughly: Water deeply after planting to settle the soil and provide initial moisture.
    8. Mulch (Highly Recommended): Apply a generous layer of organic mulch (such as leaf mold, shredded bark, or pine needles) around the base of the plant, keeping it away from the stems. Mulch is essential to retain moisture, suppress weeds, keep the soil cool, and mimic its natural woodland floor environment.

    Ongoing Care:

    • Watering:
      • Establishment: Water regularly and consistently during the first growing season, especially during dry spells, to help establish a strong root system. Keep the soil consistently moist, never allowing it to dry out completely, particularly during warmer months.
      • Established Plants: Once established, Asarum splendens prefers consistently moist soil. Water regularly during dry periods, especially in warmer weather. It is not drought-tolerant and will suffer if allowed to dry out. Monitor soil moisture and water when the top inch of soil feels slightly dry. Deep watering is best.
    • Fertilizing: Asarum splendens is not a heavy feeder. A light application of a balanced, slow-release fertilizer in early spring, or top-dressing with compost annually in spring, is beneficial. Avoid over-fertilizing.
    • Pruning: Minimal pruning is required.
      • Foliage Cleanup (Optional): You can remove any dead, damaged, or unsightly foliage as needed to maintain a tidy appearance.
      • Dividing (Optional, Very Slow): Asarum splendens spreads slowly by rhizomes and is not typically divided. It prefers to be left undisturbed. Division is possible but should only be done if necessary for propagation or if the clump becomes very congested (which is rare). Divide in early spring or fall.
    • Overwintering: Asarum splendens is generally hardy in USDA zones 5-8 (check specific hardiness for your location). It is cold-hardy within its range and generally does not require winter protection. In very cold zones or for newly planted specimens, a layer of mulch can provide extra insulation during harsh winters.
    • Pests and Diseases: Asarum splendens is generally resistant to pests and diseases. Slugs and snails may occasionally nibble on foliage, especially in very damp conditions. Good air circulation and avoiding overly wet foliage can help prevent any potential fungal issues, though these are rare.

    Enjoying Your Asarum splendens:

    • Seasonal Interest: Asarum splendens offers year-round foliage interest in milder climates due to its evergreen to semi-evergreen nature and striking foliage patterns. Spring brings new growth, and the foliage remains beautiful throughout the seasons.
    • Groundcover Beauty: Enjoy the lush, patterned carpet it creates in shady areas, providing a sophisticated and low-maintenance groundcover solution.
    • Deer Resistance: Rest easy knowing Asarum splendens is generally deer resistant!

    Pro-Tip: Consistent moisture and shade are the keys to happy and vibrant Asarum splendens. Mulch is your best friend for retaining soil moisture and creating the woodland-like conditions it loves. Avoid direct sun at all costs to prevent leaf scorch and maintain the best foliage color.

    By following these guidelines, you can successfully plant and enjoy the extraordinary beauty of Asarum splendens in your shade garden for many years to come!

    Asarum Morphology: A Closer Look

    Asarum, commonly known as wild ginger, is a fascinating group of plants with unique features. Here is a breakdown of their morphology:  

    General Habit

    • Low-growing: These herbaceous plants typically stay close to the ground, rarely exceeding 6-8 inches in height.
    • Rhizomatous: They spread horizontally via underground stems called rhizomes. This allows them to form colonies and carpets in their preferred woodland habitats.

    Leaves

    • Opposite arrangement: Leaves arise in pairs from the nodes along the rhizome.

     

    • Shape: Predominantly heart-shaped or kidney-shaped, giving them the common name "wild ginger."  
    • Texture: Can be smooth, glossy, hairy, or even textured (like in Asarum maximum).
    • Coloration: Typically shades of green, but many species and cultivars exhibit striking variegation, silver markings, or bronze hues.
    • Evergreen or deciduous: Depending on the species, leaves may persist year-round (evergreen) or die back in winter (deciduous).

    Flowers

    • Inconspicuous: Often hidden at ground level amongst the leaves.
    • Unique structure:
      • Three fused sepals form a bell-shaped or jug-like calyx. This gives them the alternate name "Little Brown Jugs."  
      • True petals are usually absent or reduced to tiny structures.
      • Colors range from brown and purple to greenish-yellow.
    • Pollination: Typically pollinated by flies or beetles attracted to the flowers' often musty or pungent odor.

    Fruits and Seeds

    • Capsules: The flowers develop into fleshy capsules containing numerous small seeds.
    • Seed dispersal: Often aided by ants, which are attracted to a fleshy appendage on the seeds (elaiosome).

    Variations Within the Group

    While the above describes the general morphology of Asarum, there's considerable diversity within the group, especially when considering the proposed segregated genera:

    • Heterotropa: Often displays more elaborate leaf shapes and patterns, with some species having elongated or almost triangular leaves.

    Asarum, also known as wild ginger, is a low-maintenance plant that thrives in shady locations with moist soil. Here is a breakdown on how to care for it in your garden:

    Lighting and Soil:

    • Light: Aim for shady or dappled sunlight. Avoid planting Asarum in full sun, especially in hot climates where the leaves can scorch.
    • Soil: The key is well-drained soil rich in organic matter that retains moisture. Amending the planting area with compost or aged manure before planting is highly recommended. Asarum prefers slightly acidic soil with a pH between 5.5 and 6.8. You can test your soil's pH with a home testing kit available at most garden centers.

    Watering and Feeding:

    • Watering: Water regularly, especially during the first growing season and during hot or dry spells. Aim to keep the soil consistently moist but not soggy. Asarum tolerates short periods of drought but will perform best with consistent moisture.
    • Feeding: Asarum is not a heavy feeder, but a light top dressing of compost in spring can be beneficial.

    Other Care Tips:

    • Mulching: Apply a layer of mulch around your Asarum plants to help retain moisture, suppress weeds, and regulate soil temperature. Aim for a 2-3 inch layer of organic mulch, such as shredded bark or compost.
    • Dividing: You can propagate Asarum by dividing established clumps in early spring. Dig up the clump carefully and use a sharp knife to divide it into sections, each with healthy roots and shoots. Replant the divisions immediately.
    • Pests and Diseases: Asarum is generally resistant to pests and diseases. However, keep an eye out for slugs and snails, which can damage the foliage. You can handpick these pests or use organic control methods such as beer traps or diatomaceous earth.

    Additional Tips:

    • Deadhead spent flowers to encourage additional blooms.
    • Asarum is slow-growing, so be patient and do not expect it to fill in overnight.
    • Enjoy the beautiful foliage and unique charm that Asarum brings to your shade garden!

    Asarum plants have a bit of an interesting relationship with pollinators. Here is the breakdown:

    ·Yes, but not primarily: Asarum flowers do attract some pollinators, but they are not particularly showy or fragrant. The small, brownish flowers are often hidden beneath the leaves.

    • ·Beetles, flies, and ants are visitors: The main pollinators of Asarum are small insects like beetles, flies, and ants. These insects are attracted to the flower's dull color and mild odor, which can resemble decomposing organic matter. While they may visit the flower for these reasons, it is not guaranteed they will cause pollination.
    • ·Self-pollination is key: In fact, many Asarum species, particularly the eastern North American variety (Asarum canadense), are primarily self-pollinating. The flower structure allows pollen from the male parts to easily reach the female parts of the same flower, ensuring seed production even without the help of pollinators.

    So, while Asarum does attract some pollinators, they are not the main focus of the plant's reproductive strategy. Self-pollination takes precedence for Asarum.

    The good news is that Asarum is generally considered a low-maintenance plant and relatively resistant to pests and diseases. However, there are a few things to keep an eye out for:

    • Slugs and Snails: These slimy mollusks love to munch on tender foliage, and Asarum's leaves can be a target. You can handpick these pests at night when they are most active or use organic control methods such as beer traps or diatomaceous earth.
    • Fungal Diseases: In very moist conditions or with poor drainage, fungal diseases like root rot can occur. Ensuring proper drainage and avoiding overwatering is key to preventing this.

    Here are some additional tips to keep your Asarum healthy:

    • Maintain good air circulation: While Asarum prefers shade, avoid overcrowding plants. Good air circulation helps prevent fungal diseases.
    • Remove fallen leaves: Cleaning up fallen leaves around the base of the plant can help reduce the risk of disease and attract fewer pests.
    • Monitor for signs of trouble: Keep an eye out for any changes in your Asarum's foliage, such as wilting, yellowing, or holes in the leaves. Early detection and treatment can help prevent problems from worsening.

    By following these tips, you can help your Asarum thrive in your shade garden for many years to come.

    While Asarum has beautiful foliage, it would not be the most ideal choice for floral arrangements for a few reasons:

    • Flowers: The main drawback is the flowers themselves. Asarum flowers are small, inconspicuous, and often hidden beneath the leaves. Their brownish or reddish color would not add much visual interest to an arrangement.
    • Leaf fragility: While the heart-shaped or kidney-shaped leaves are attractive, they can be delicate. They might wilt or bruise easily during handling and arranging.
    • Short vase life: Asarum is not typically grown as a cut flower, and the foliage may not have a long lifespan in a vase.

    Better alternatives for floral arrangements:

    If you are looking for shade-loving foliage for arrangements, consider these options with longer-lasting and more visually striking features:

    • Hosta: Hosta offers a variety of leaf shapes, sizes, and colors that can add texture and interest to bouquets.
    • Ferns: Lacy fronds of ferns come in various shades of green and can add a delicate, airy touch.
    • Begonia: Certain begonia varieties boast beautiful foliage in shades of green, burgundy, and even with metallic sheens.
    • Caladium: Caladiums are known for their vibrantly colored, patterned leaves, perfect for adding a bold statement.

    Using Asarum in potted arrangements:

    While Asarum might not be the best for cut flower arrangements, you could consider using it in potted container displays. Here, the plant can thrive in its preferred growing conditions and add a touch of shade-loving greenery to your floral composition.

    The invasiveness of Asarum depends on the specific species and the local environment. Here is a breakdown:

    • Generally, Not Invasive: Most Asarum species, particularly the popular varieties like Canadian Wild Ginger (Asarum canadense) and European Wild Ginger (Asarum europaeum), are not considered invasive. They are slow to moderately spreading plants and are unlikely to take over a garden bed.
    • Fast Spreading in Ideal Conditions: However, under ideal conditions with consistently moist soil and plenty of shade, some Asarum species can become more vigorous spreaders. They may spread by underground rhizomes and potentially crowd out other plants.
    • Consider Native vs. Introduced Species: If you are concerned about invasiveness, it is generally recommended to choose native Asarum species for your area. Native plants are less likely to become aggressive and can support the local ecosystem.

    Here are some resources to help you identify Asarum species native to your area:

    Controlling Asarum Spread (if needed):

    If you find your Asarum spreading more than desired, here are some methods for controlling it:

    • Physical Barriers: You can install edging around the planting area to restrict the spread of underground rhizomes.
    • Division and Replanting: Dig up and divide established clumps but be cautious not to unintentionally encourage further spread by leaving behind root fragments.
    • Herbicides (as a last resort): Herbicides should be a last resort and should only be used according to the label instructions for specific Asarum species.

    By understanding the growth habits of your specific Asarum variety and planning accordingly, you can enjoy this shade-loving perennial in your garden without worrying about invasiveness.

    The best time to propagate Asarum depends on the method you choose:

    • Division: Early spring (just as new growth emerges) is considered the best time to propagate Asarum by division. The cool soil temperatures and increased moisture levels in spring favor successful root establishment for the divided sections.
    • Seed: Propagating Asarum by seed is a slower process and requires patience. If you choose this method, collect seeds when the seed capsules start to split open, typically in fall. You can sow the seeds directly outdoors in a shaded location with moist soil or start them indoors in pots with a well-draining potting mix. Seeds can take several months or even a year to germinate.

    Here is a quick summary table:

    Propagation Method

    Best Timing

    Division

    Fall (seed collection) or stratification period followed by sowing indoors or outdoors

    Additional Considerations:

    • No matter which method you choose, ensure you have the proper tools (sharp knife for division) and suitable growing conditions for the new plants.
    • For successful propagation by division, choose healthy, mature Asarum plants.
    • Regardless of the timing, proper care after propagation is crucial for the Asarum's survival. Maintain consistent moisture, provide shade, and avoid disturbing the newly propagated plants until they establish themselves.

    Here are the benefits of planting Asarum in your garden:

    • Beautiful Shade-loving Foliage: Asarum offers a lush carpet of attractive heart-shaped or kidney-shaped leaves throughout the growing season. Depending on the variety, the leaves can be evergreen or deciduous and come in various shades of green, some with interesting patterns or variegations. This makes them a perfect choice for adding year-round greenery to shady areas of your garden.
    • Low-Maintenance Groundcover: Asarum is a low-maintenance plant that thrives with minimal care. Once established, it requires moderate watering and does not need frequent fertilization. It also spreads by underground rhizomes, helping to suppress weeds and create a dense groundcover.
    • Deer and Rabbit Resistant: Asarum is unpalatable to deer and rabbits, making it a good choice for gardens prone to these pests. You can enjoy your Asarum plants without worrying about them being munched on by herbivores.
    • Attracts Beneficial Insects: While not the showiest flowers, Asarum blooms do attract some beneficial insects like beetles and flies. These insects may contribute to pollination and can help control other pest populations in your garden.
    • Adapts to Various Soil Types: While Asarum prefers moist, well-drained soil rich in organic matter, it can tolerate a range of soil conditions, including clay loam. This makes it adaptable to different garden settings.
    • Slow Erosion Control: The dense groundcover formed by Asarum can help prevent soil erosion on slopes or in areas with heavy rain.
    • Easy to Propagate: Asarum can be easily propagated by dividing established clumps in early spring. This allows you to expand your Asarum plantings or share them with others.

    Overall, Asarum is a versatile and low-maintenance plant that offers a multitude of benefits for shade gardens. From its beautiful foliage and low-growing habit to its deer resistance and ease of propagation, Asarum can be a valuable addition to your landscaping.

    Asarum Species, Groups and Cultivars

    It is tricky to give you a definitive list of Asarum species, groups, and cultivars because the classification is in flux! But I can offer some info based on both the traditional and emerging views:

    Traditional Grouping (Asarum as one big genus):

    • Popular Species:
      • Asarum canadense (Canadian Wild Ginger): North American native, large heart-shaped leaves, deciduous.
      • Asarum europaeum (European Wild Ginger): Glossy, evergreen leaves, compact habit.
      • Asarum caudatum (Western Wild Ginger): West Coast native, long-tailed flowers.
    • Cultivar Examples (often of uncertain origin):
      • 'Eco Choice' (denser A. canadense)
      • 'Eco Red Giant' (larger A. canadense)
      • 'Silver Streak' (variegated leaves)  
      • 'Hartford Bronze' (bronze-tinged leaves)

    Emerging Groups (Asarum split into multiple genera):

    This is where it gets complex, as not all botanists agree on the splits. Here is a simplified overview:

    • Asarum sensu stricto:
      • Mostly Asian species (e.g., Asarum maximum with striking patterned leaves)
      • Some North American (e.g., Asarum shuttleworthii)  
      • European Wild Ginger likely stays here
    • Heterotropa:
      • Many Japanese species with diverse leaf shapes and patterns (e.g., Heterotropa takaoi, Heterotropa catesbaei)
      • Often sought after by collectors
    • Hexastylis:
      • North American species (e.g., Hexastylis arifolia with arrowhead leaves)
      • Sometimes called "Little Brown Jugs" due to flower shape
    • Asiasarum & Geotaenium:
      • Fewer species, less commonly cultivated

    Cultivars in this system:

    • Harder to pinpoint, as many cultivars arose before the splits were widely accepted
    • You might see names like Heterotropa 'Chameleon' or Hexastylis 'Eco Choice' if sellers are using the newer taxonomy

    To find more specific info:

    • Search by the scientific name: If you know the species or cultivar name, which is your best bet.
    • Use image search: Visuals can help you narrow down what you are looking for.
    • Check reputable nurseries: They often list plants by both common and scientific names and may have info on the newer classifications.

    I hope this gives you a good starting point for exploring the wonderful world of Asarum!

    Here's how Asarum spp. and the genus Hexastylis relate:

    • Historically: All wild gingers were lumped together under the genus Asarum. This included species with quite a bit of variation in traits like leaf shape, flower structure, and chromosome number.
    • Modern Shift: Botanists have been increasingly recognizing that Asarum as traditionally defined is actually a group of closely related but distinct lineages. This has led to proposals to split it up.
    • Hexastylis' Place: Hexastylis is one of the proposed segregated genera. It contains roughly 10 species, all native to North America. They tend to have:
      • Evergreen leaves
      • Distinctive "jug-shaped" flowers (hence the nickname "Little Brown Jugs")
      • A specific chromosome number that differs from many other wild gingers
    • Key Point: Hexastylis used to be considered a separate genus, then got lumped into Asarum, and now is in the process of potentially being split back out!
    • Why the Debate? Plant classification aims to reflect evolutionary relationships. Evidence from morphology (appearance), genetics, and even fossil records is used. Sometimes, as in the case of Asarum, there's ongoing research and not full agreement yet.
    • Practical Impact:
      • Scientific Names: You might see a plant labeled as Asarum arifolium (older) or Hexastylis arifolia (newer). Both refer to the same species.
      • Gardening: Whether lumped or split, the care requirements for these plants are usually similar (shade, moist soil, etc.).
      • Understanding Diversity: Recognizing the distinctions helps us appreciate the variety within wild gingers.

    In Summary:

    • Asarum spp. is the broader term, encompassing all wild gingers.
    • Hexastylis is a group within that, likely deserving of its own genus status based on current evidence.
    • The taxonomy is still being refined, so you will see both names used.
