Thriller Lady's Mantle

Thriller Lady's Mantle (Alchemilla mollis 'Thriller') is a lush, mounding perennial groundcover renowned for its velvety, scalloped leaves that perform a daily magic trick — catching and beading morning dew and rainwater into glittering silver pearls. This superior selection of the classic cottage garden staple offers an especially vigorous, large-leaved habit, forming impressive, weed-suppressing mounds of soft gray-green foliage. In late spring and early summer, frothy sprays of chartreuse-yellow flowers billow above the foliage in an airy, romantic cloud.

Developed from Professional Grade root systems, Thriller Lady's Mantle is as hardworking as it is beautiful. Its dense, spreading mounds serve as a superb groundcover under shrubs and roses, along shaded pathways, and at the front of mixed borders where its soft texture and chartreuse flowers provide a graceful, unifying element. This adaptable perennial handles everything from full sun to deep shade and thrives in the cool, moist conditions of Pacific Northwest and woodland gardens.

These 4" healthy live plants thrive in full sun to full shade in moist, humus-rich, well-draining soil. In hot climates, afternoon shade is strongly recommended to prevent leaf scorch. Water consistently — Lady's Mantle prefers evenly moist conditions and will flag in prolonged drought. Best suited for USDA Hardiness Zones 3–8. Mature height in bloom: 12–18 inches; spread: 18–24 inches. Blooms late spring to early summer. Cut back hard after blooming if foliage looks tired; fresh, vigorous new growth will emerge quickly.
