Glistening white flowers in early summer. Stunningly beautiful when used alone or in combinations in the landscape, Astilbe is attractive from spring to late fall. Upright clusters of colorful blooms are eye-catching in every stage of maturity. Tight flower clusters open slowly to present feathery plumes. The clusters often dry in place and these dried plumes can last well into the fall. Moisture lovers!
