Astilbe simplicifolia 'Key West'

Key West False Spirea

A refined simplicifolia-type astilbe noted for its glossy, finely cut foliage and soft rose-pink flower plumes. Lighter and more delicate in appearance than Arendsii types, ‘Key West’ is ideal for front-of-border and detailed shade plantings where texture matters.
