These clumping, deciduous perennials have ferny leaves and tall, feathery spikes of reddish flowers in spring and early summer. The best bloom occurs in full to part sun to 24-30". They make an excellent cut flower, requiring average watering.

Grow in average to loamy, medium, well-drained soils in part shade to full shade. Prefers moist, humusy, organically rich soils. If regularly watered, foliage will usually remain attractive throughout the growing season. Mulch helps retain soil moisture. Chinese astilbes are generally noted, however, for having better sun and drought tolerance than other species of astilbe. Removing faded flower stalks will not prolong bloom but may improve plant appearance, particularly if a ground cover look is desired. On the other hand, many gardeners leave the flower stalks in place after bloom because of the continuing ornamental interest of the dried seed heads. Divide clumps when overcrowding occurs (every 3-4 years). Not a low-water plant, but one of those that is habitually over-watered.
