Physical description: Lady's mantle forms clumps that may reach 24
in. wide; basal foliage is 8-10 in. tall with flower stems that
reach 18 in. tall. The deciduous leaves are green, palmately
veined with 7 to 11 shallow-toothed lobes, and are softly hairy.
Basal leaves are 2 to 4 in. wide. Flowering occurs in late spring
to early summer, but the period of bloom may be reduced in a
warm or dry climate. Flowers are greenish yellow, each reach
a diameter of 1/8 in., and are borne in compound cymes. This
species is often confused with Alchemilla vulgaris, which
is very similar but a little bit smaller, with leaves that are
more hairy, and flowers slightly larger and a bit more yellow.
Optimal growing conditions: Lady's mantle performs best in moist, well-drained,
organically rich soil that is neutral to slightly acidic. In
regions with cool and moist climates, this plant can tolerate
full sun or partial shade, but if the climate is hot or dry,
it needs a location in partial shade. Winter hardiness: Zones
4-7. This species sometimes reseed itself and may become invasive:
if it becomes a problem, its spread can by limited by removing
the flowers shortly after they fade.
Susceptibility to pests and diseases: Lady's mantle has no serious insect or disease
problems, but in climates with hot nights, water collected in
leaf depression may promote growth of fungus.
Use:
Used as a ground cover or in front of a border, Lady's mantle
is very useful, especially in regions with cool summers.
