About 20 species of annuals and herbaceous perennials from Europe and Asia. The perennials are clump-forming with dissected leaves and buttercup-like flowers usually composed of eight to twenty petals though some species have more, others less.
Suitable for the rock garden, raised bed or alpine house, both for their flowers and ferny foliage. Most ordinary well drained soils are suitable in an open sunny site. Propagation of perennials by careful division in spring or early summer, or by seeds when ripe, in a cold frame. Annuals best sown in situ in spring.
