Astilbe is a perennial plant that calls mountain terrain, ravines, and forests of Asia and North America home. There are a great many different species for us to use in landscaping, resulting from patient crossbreeding giving rise to hundreds of hybrids.
Different hybrids show off their bloom at various times, usually from June through August. They’re undeniably a beautiful sight with their fluffy flower plumes. Colors are usually in shades of red, white, pink, and cream.

Planting spot and use in water gardens
Astilbe thrives in direct sunlight. However, leaves might get a little sunburned and crinkly in intense heat. Thus, it’s best to find spots with dappled sunlight, or garden areas that only get about three to four hours of sun a day. Part shade and shade is more to their liking.
