Astilbe is a genus of 18 species of perennial, herbaceous flowering plants, within the family Saxifragaceae. Some species are commonly known as False Goat's Beard, and False Spirea. Astilbe species are native to Asia and North America.
These hardy, herbaceous perennials are cultivated by gardeners for their large, handsome, often fern-like foliage, and dense, feathery plumes of flowers. Astilbes are widely recognized for their profuse blooms in full shade. They are widely adapted to water-logged conditions, and tolerate clay soils well. Numerous hybrids have been raised. Astilbe is a tall feathery flowered plant popular as a pond side feature, due to its previously described growing conditions.
