Astilbe arendsii

Astilbe is a clump-forming perennial with finely divided, fern-like foliage and feathery plumes of tiny flowers in shades of pink, red, white, lavender, and salmon from early to midsummer. Hybrid origin (A. chinensis x A. japonica x others), developed by Georg Arends in the early 1900s. Reaches one to four feet tall depending on cultivar.

Grow in partial shade in moist, humus-rich soil. Astilbe does not tolerate drought; consistent moisture is essential. Flower plumes dry on the plant and provide winter interest if left standing. Divide clumps every three to four years to maintain vigor. Few serious pest or disease issues; Japanese beetles may feed on foliage in some regions.
