Lady’s mantle, Alchemilla mollis, is an old-fashioned, tough and adaptable European garden perennial grown for both its interesting foliage and frothy sprays of flowers. It is the most commonly planted of nearly 300 species in the genus in the rose family (Rosaceae) native to the mountains of Europe, Asia, and North America. Its common name supposedly comes from the resemblance of its scalloped leaves to the Virgin Mary’s cloak, although other explanations exist. Native to Turkey and the Carpathian Mountains, A. mollis has been used medicinally for stomach ailments and to dye wool green. Lady’s mantle should be planted with care as it can be invasive because of its abundant seed production. It is hardy in zone 3-8.
The large leaves are lobed, with serrated edges.

The soft, velvety leaves are up to 6” across with serrated edges. Each leaf is palmately veined with 7-11 partially folded lobes, making it appear pleated. The foliage is light green to olive green in color. Plants spread very slowly by rhizomes, forming mounds 12-15” tall that spread to two feet or more.
Numerous, long hairs on the leaves catch and hold water droplets.

The dense hairs on the leaves catch and hold water droplets, so are very attractive after a rain or in the morning when drops of dew collect on the textured leaves like a sprinkling of diamonds or beads of liquid mercury. These beads of water were considered by alchemists to be the purest form of water, and they used this water when attempting to turn base metal into gold – hence the name “Alchemilla”.
The tiny flowers, closeup, have no petals.
Airy sprays of yellow to chartreuse flowers cover the plants in early to midsummer. The individually inconspicuous, ¼” wide, star-shaped flowers have no petals.
The plants produce airy sprays of yellow to green flowers.
The effect is fairly subtle, compared to many perennials with bold, brightly colored flowers, and some gardeners prefer to cut off the flowers. Cut stems make good fillers in cut flower arrangements, but fresh and dried.
The flower stems tend to flop after a while.

To dry, just hang cut stems in bundles upside down in a cool, ventilated spot until dry. They resist shattering and last longer than many dried flowers.
The flower stems tend to flop over after a while, making the plants look somewhat messy. There are no seedpods; the tiny brown seeds are held in the calyx, which becomes brown and papery when the seeds are ripe, with one seed per flower. Shear after blooming to improve the plant’s appearance and prevent self-seeding. New, lush basal growth will begin growing soon after trimming and this foliage should remain good looking through the remainder of the season.
An easy-care perennial, it does well in sun or partial shade. In hot climates it may scorch in full sun, but this is rarely a problem in the upper Midwest. It tolerates most soils, except overly moist conditions, and does well in clay.
The foliage in late winter and early spring.

It is not drought tolerant and should be watered when soil moisture is lacking. The foliage will turn completely brown over the winter and new leaves appear in spring. It is best to shear the old leaves from the crowns in early spring before new growth starts.
Use lady’s mantle at the front of the border, in cottage gardens or as a ground cover. It looks really good spilling over the edge of a path, especially when in bloom. It could even be used in large containers.

The soft, mounding appearance of this plant contrasts nicely with vertical perennials such as iris, liatris, ferns, and salvia (when in bloom) and the boldly textured, soft-colored foliage looks great in combination with dark green or purple leaved plants, and with finer textured plants. The cooling yellow-green or green-yellow of the flowers is a superb companion to almost all colors, but especially violet, blue, and pink. The blooming plants complement pink shrub roses nicely.
A. mollis is easily propagated by seed (and readily self seeds in many gardens, to the point of being invasive in ideal growing conditions). Seedlings are easily identifiable, as they have the same three-lobed leaves as the adult plants. Volunteers are easily weeded out or moved. It will take at least two years from seeding until plants bloom. Established clumps can be divided in spring or fall, although early spring is best. It has almost no pests and is not favored by deer.

A. mollis is the most widely grown of the genus and only a few cultivars are available (and seem to be rather similar):

  • ‘Auslese’ is a European selection, chosen for its more upright, lime-green flowers. The plant is larger than the species (15-18” tall).
  • ‘Irish Silk’ grows to 2 feet tall and is particularly florific.
  • ‘Robusta’ is more upright with larger leaves than the species, growing to 2 feet tall and wide.
  • ‘Thriller’ is a slightly more compact variety with flowers that tend more toward green than yellow.

Other species sometimes available include:

  • A. alpina (mountain lady’s mantle) – a mat-forming species only 3-8” tall that needs good drainage, so would be good for rock gardens. The deeply lobed leaves have silvery-white margins. Zones 3-7.
  • A. conjuncta appears similar to A. alpina, but is larger and is hardy in zones 3-7.
  • A. ellenbeckii is a low-growing species (~2” high) with red stems and sliver-edged foliage, only hardy to zone 6.
  • Alchemilla erythropoda.
    Alchemilla erythropoda

    A. erythropoda – looks like a miniature version of A. mollis with yellow flowers, only growing 5-6” tall. It is another good choice for the rock garden, troughs or small spaces. Zones 3-7.
  • A. faroensis is a dwarf species from Eastern Iceland that only grows a few inches tall and is hardy in zones 4-7. The cultivar ‘Pumila’ is only 2-3” tall and is well suited to growing in a trough.
  • A. fulgens, from the Pyrenees, is a low-growing, spreading species with bluish-green leaves. Zones 4-7.
  • A. sericata ‘Gold Strike’ is a new introduction from Jellito, with smaller, deeply lobed leaves on 12-14” plants promoted as a ground cover.
