Pure white summer plumes rise above glossy, dark green divided leaves on Astilbe Washington, bringing a clear flower display to moist, shaded borders.
This clump-forming perennial suits cottage beds, woodland edges, pond margins, and cutting gardens. The flowering stems attract butterflies and can be cut for fresh or dried arrangements. Leave faded spikes in place for autumn and winter interest, then remove them in spring.
Choose partial shade and moist, well-drained or boggy soil. In full sun, the soil must stay moist because drought and hot sun can scorch the foliage. Divide established clumps in late winter or early spring when more plants are needed.
