Astilbe (white)
Genus of about 12 species of densely clump-forming, rhizomatous perennials from moist sites in mountain ravines, woodland, and streambanks in S. E. Asia and North America. They are grown for their striking, plume-like panicles, 18-35cm (7-14in) long, of tiny, red, pink, purple, or white flowers, borne mainly in summer.

Grow in moist, humus-rich soil or boggy sites in full sun; in drier soils grow in partial shade. Astilbes prefer fertile soil and will not thrive in chalky or clay soils that dry out in summer. Divide and replant every 3 or 4 years to maintain vigour and flower quality, discarding old, wood rhizomes. The flowers and young foliage may be damaged by late frosts.
