Astilbe is a genus of 18 species of rhizomatous flowering plants within the family Saxifragaceae, native to mountain ravines and woodlands in Asia and North America. Astilbes, known by common names, False Goat’s Beard and False Spirea, are excellent for creating a soft, colorful display underneath trees, in low light corners, or in shady borders. Spirea plants are great because they are pest free and attract birds and butterflies. Blooms in purple, red, pink, and white with a soft blue green foliage color.
