Three-leaved anemone (Anemone trifolia)

Description

Anemone trifolia, the three-leaved anemone, is a perennial herbaceous plant in the genus Anemone (Ranunculaceae). The plant has stems growing 10–30 cm tall and bear single, white (rarely pale pink or pale bluish) flowers two centimetres in diameter, with five to nine (most often six) elliptical tepals. The fruit is a cluster of 2 mm achenes. Its leaves are divided into three lanceolate leaflets and form a single whorl of three leaves per stem; the leaflets have a toothed but not lobed margin. The rhizome, found directly below surface is whitish, and tends to form dense clonal colonies. In subsp. albida, the achenes are pendulous. The species differs from A. nemorosa in its white or pale blue anthers (unlike the yellow anthers of A. nemorosa) and simple lanceolate leaflets lacking the deep lobing of A. nemorosa. The flowering period extends from April through June.
