Alchemilla micans aka Gleaming Lady's Mantle

Taxonomy ID: 9287

Alchemilla micans, commonly known as Gleaming Lady's Mantle or Shining Lady's Mantle, is a medium-sized herbaceous perennial in the rose family (Rosaceae). This species was first published by Buser in 1893 and has historically been widely known as Alchemilla gracilis Opiz, though that name has since been determined to more properly refer to A. monticola.

The plant features dark green foliage that often has a somewhat sericeous (silky) appearance due to fine hairs on the abaxial (lower) surface of the leaves. Some specimens may develop reddish-brown coloration, particularly on exposed distal parts of stems and inflorescences. The stems are usually densely covered with spreading to slightly ascending hairs, though they are typically glabrous (hairless) in the upper half. Plants typically grow to heights of 30-50 cm (12-20 inches) with a similar spread.

As a perennial apomict (reproducing asexually through seeds without fertilization), Alchemilla micans typically flowers earlier in the year than most related Alchemilla species, usually beginning in May. The flowering period extends through September, with seeds typically shed by late June or early July. After seed dispersal, the inflorescence becomes relatively inconspicuous.

This species grows primarily in the temperate biome, favoring meadows, moist sand, and well-drained pastures at elevations from sea level to 400 meters. It thrives in species-rich grazed pastures on shallow soils, including those overlying limestone. The native range extends from Europe to Siberia, encompassing Austria, the Balkans, Scandinavia, and central and eastern Europe westward to southern France and Italy, and eastward to western Siberia.

Alchemilla micans has been introduced to northeastern North America, where it has naturalized in parts of Newfoundland and Labrador, Nova Scotia, Quebec, Maine, and New York. In Britain, the species was not formally recognized until 1976 and is currently known only from Northumberland, where it holds a conservation status of Vulnerable. While not threatened at the European level, the species is classified as potentially invasive in some regions outside its native range.

How easy is it to grow Alchemilla micans?

Alchemilla micans is an easy-care perennial that requires minimal attention once established. It tolerates a wide range of soil types and light conditions, is naturally pest and disease resistant, and even deer and rabbits avoid it. The plant is notably untroubled by slugs and snails thanks to its downy leaves. Simply provide moderate moisture, avoid waterlogged conditions, and deadhead spent flowers to prevent excessive self-seeding.

How often should I water Alchemilla micans?

💧 Moist

Alchemilla micans prefers consistently moist but not waterlogged soil. About an inch of water per week is sufficient for established plants. Newly planted specimens should be watered regularly throughout their first summer to help establish strong root systems. While the plant handles brief dry spells better than many leafy perennials, avoid letting it sit in dried-out soil for extended periods. Container-grown plants require more frequent watering as potting mix dries quickly.

What type of soil does Alchemilla micans need?

pH: Acid to neutral Any soil

Alchemilla micans is remarkably adaptable to different soil types. It grows well in chalky, loamy, clayey, or sandy soils, performing best in soil with a pH between 5.5 and 7.5. The most important factor is drainage - avoid waterlogged conditions while maintaining some moisture. In its native habitat, it thrives in species-rich grazed pastures, including those on shallow soil overlying limestone, demonstrating its soil adaptability.

What light conditions does Alchemilla micans prefer?

Alchemilla micans thrives in both sun and partial shade, making it versatile for various garden positions. It grows well in conditions ranging from half shade to full sun. In hot climates or regions with intense summer sun, some afternoon shade helps prevent leaf scorch. The species naturally occurs in meadows and woodland edges where dappled light is common.

How do I propagate Alchemilla micans?

Division is the easiest method for propagating Alchemilla micans. In early spring or autumn, lift the plant and split clumps using a sharp spade, selecting younger outer sections approximately 15cm across. Replant divisions immediately and water well. For seed propagation, collect ripe seeds in late summer and sow them in pots, surface-sowing or lightly covering with soil. Keep in a sheltered outdoor location or coldframe, as seeds benefit from cold stratification. Germination typically takes 14-30 days.

How big does Alchemilla micans grow?

Moderate

Alchemilla micans is a medium-sized perennial typically reaching 30-50 cm (12-20 inches) in height with a similar spread of 45-60 cm (18-24 inches). It forms attractive clumps of dark green, silky foliage that can develop reddish-brown tints on exposed stems. As a perennial apomict, it grows at a moderate rate and may take a couple of seasons to reach full size. The plant dies back completely in winter, with new leaves emerging in spring.

Where is Alchemilla micans native to?

Alchemilla micans is native to Europe and extends eastward into Siberia. Its range encompasses Austria, the Balkans, Scandinavia, and much of central and eastern Europe, extending from southern France, Italy, and Greece northward to southwest Norway and eastward to western Siberia. The species has been introduced to northeastern North America where it has naturalized in parts of Newfoundland, Nova Scotia, Quebec, Maine, and New York.

When and how does Alchemilla micans flower?

🌸 May-September

Alchemilla micans flowers from late May through September, typically blooming earlier than most related Alchemilla species, with flowering usually beginning in May. The plant produces small yellowish-green flowers in loose clusters above the foliage. Seeds are shed by late June or early July, after which the inflorescence becomes relatively inconspicuous. As a perennial apomict, the plant produces viable seeds without requiring pollination.

Does Alchemilla micans need fertilizer?

Alchemilla micans generally does not require fertilizing. The plant grows readily on its own without additional nutrients. Applying organic mulch around the base in spring helps retain soil moisture and gradually improves soil structure as it breaks down, which is usually sufficient to maintain healthy growth. Avoid adding fertilizer as it can encourage excessive, floppy growth.

How do I prune Alchemilla micans?

By late July, cut Alchemilla micans back to the base to encourage a flush of fresh, attractive foliage. Water the plant well after cutting back. Deadhead spent flowers throughout the season to prevent excessive self-seeding, as the plant can spread freely in favorable conditions. In autumn, you can either cut back faded foliage or leave it in place to provide winter shelter for beneficial insects. Remove old foliage in early spring before new growth emerges.

Can Alchemilla micans grow outdoors in my climate?

🇺🇸 USDA 3-8

Alchemilla micans is a hardy outdoor perennial suited to USDA zones 3-8, tolerating cold winters down to approximately -40°C (-40°F). It thrives in temperate climates and naturally goes dormant in winter, re-emerging in spring. The plant prefers cool to moderate temperatures and may struggle in hot, humid climates, particularly if exposed to intense afternoon sun. In its native European and Siberian range, it grows from sea level to 400 meters elevation.

What pests and diseases affect Alchemilla micans?

Alchemilla micans is remarkably resistant to pests and diseases. The downy texture of its leaves makes it unpalatable to slugs and snails, which typically avoid it. Deer and rabbits also generally leave the plant alone. There are no significant disease problems associated with this species. The main concern is not a pest but the plant's tendency to self-seed prolifically if spent flowers aren't removed.

What temperatures does Alchemilla micans tolerate?

Alchemilla micans is cold-hardy and thrives in temperate climates. It tolerates winter temperatures down to approximately -40°C (-40°F), going fully dormant and dying back to the ground in winter before re-emerging in spring. The plant prefers cooler growing conditions and may struggle in extreme heat, particularly with intense direct sun. In warm climates, provide afternoon shade to prevent leaf scorch.

Does Alchemilla micans have medicinal uses?

💊 Rating 3/5

Alchemilla species, including A. micans, have a long history of medicinal use dating back to medieval times. Traditional uses include treating digestive issues, wounds, and various women's health concerns. The plants contain tannins that provide astringent properties, making them useful for wound healing and treating diarrhea. However, for medicinal purposes, A. vulgaris and A. mollis are more commonly documented and used. Always consult a healthcare professional before using any plant medicinally.

How does Alchemilla micans care change by season?

In spring, remove any old dead foliage before new growth emerges and apply a layer of organic mulch. Through summer, water during dry spells and deadhead spent flowers to prevent self-seeding. By late July, you can cut the plant back hard to encourage fresh foliage. In autumn, either remove faded foliage or leave it to provide winter insulation for the crown and shelter for beneficial insects. In winter, the plant is fully dormant underground and requires no care.
