Evergreen perennial species originating from Central European damp woodlands. Emerging from creeping rhizomes with short stems clothed in 3-parted evergreen leaves, forming an ideal gentle ground cover. Topped April to June by slender inflorescences of white open cup-shaped flowers in loose heads. Height 10-15cm. Easily grown in partial or full shade given a bit of moisture in the soil, although quite drought tolerant for moderate periods.
