    A. splendens

    Distribution Asarum splendens originates from south-central China, flourishing in moist forest openings, grasslands, and slopes. It typically grows at elevations between 800-1,300 meters. While generally hardy in USDA zones 6-9, Asarum splendens may overwinter in zone 5 with protection.

    Habitat This wild ginger thrives in moist, slightly acidic organic soil with good drainage. This preference for shade makes it a suitable choice for woodland gardens or shaded border areas. In its native environment, it grows on forest floors in full to partial shade.

    Description Asarum splendens is a low-growing, rhizomatous perennial, typically reaching a height of 6-8 inches. It spreads via short rhizomes, creating a dense mat of foliage, making it an excellent groundcover. Notably, it boasts the largest leaves of any Asarum species. These leaves are large, heart-shaped, and glossy, with a dark green color and striking silvery-white variegation. Images of Asarum splendens display its unique foliage and flower structure (see ).

    In early spring, Asarum splendens produces unusual flowers beneath its foliage. These flowers, around the size of a silver dollar are dark purple to brown in color. While not particularly showy, they possess an "interestingly attractive" quality that rewards closer inspection. Furthermore, this wild ginger exhibits a moderate growth rate, spreading "swiftly enough to achieve satisfying coverage but not so fast as to be rampantly difficult to control.

    Uses Asarum splendens is primarily cultivated as an ornamental plant, prized for its attractive foliage. It excels as a groundcover in shady areas and thrives in containers. Its substantial leaves provide "bolder foliage than the typical evergreen groundcovers," making it a distinctive choice for gardeners. In landscaping, it serves as an effective "flooring" beneath larger plants like azaleas, aucuba, or hydrangeas. While the plant's rhizomes have a ginger-like aroma when crushed, they are not related to culinary ginger and are considered toxic.

    By carefully planning and implementing a mass planting of Asarum, you can transform your landscape into a captivating and low-maintenance haven.

    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:

    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.
