Genus - Astilbe
Astilbe are also called false spirea. There are 18 species in the genus and are considered hardy herbaceous perennials. The name Astilbe is derived from the Greek "a" meaning without and "stilbe" meaning brilliance. This is in reference to the lack of shininess in the leaves of most astilbe.
Astilbe grow rhizomes, meaning they have subterranean stems that also send out roots. They prefer shade to part sun sitings. They can tolerate moist and/or clay soils though they prefer rich, humus soil. They range in height from 6" to over 5'. Mainly prized for their beautiful flower stalks and fern like foliage. Astilbes have good deer resistance.
