Two species of evergreen prostrate shrubs from circumpolar and cool climate countries further south. They have simple, densely borne leathery leaves and eight to ten-petalled solitary flowers rather like anemones. The seed heads are a cluster of achenes each with a long, white to buff plume-like style and are almost as decorative as the flowers.
Excellent rock garden plants, D. octopetala being especially desirable. Easily grown in alkaline, well drained soil in an open sunny site. Does not thrive for long in acid soils. Propagation by seed ideally when ripe or as soon after as possible, by late summer cuttings, or layering in early spring.
