Botanical Name

Plant Common Name

Astilbe, False Spirea, William Buchanan False Spirea

General Description

William Buchanan astilbe is a dwarf, clump-forming, herbaceous perennial that produces 2-ternate, red-tinted leaves and a striking plume-like inflorescence of white flowers with red stamens in mid and late summer. Thus, the inflorescence looks pink. The flowerheads fade to attractive shades of brown in the fall, providing landscape interest through winter.

'William Buchanan' requires well-drained, moist soils in full sun to partial shade. The function best in shade borders, rock gardens, or as a massed groundcover under trees. It should be divided every 3-4 years when overcrowding occurs.
