Overview
Astilbe plants are long-blooming, and consist of several species and cultivars, some spikier or fluffier than other. Astilbe does best in regions with cool, moist summers. Use in woodland gardens and along waterways with other shade-loving perennials, such as hostas and ferns.
Common problems
While Astilbe is relatively pest and disease resistant, occasionally it can develop powdery mildew or bacterial leaf spots.
Harvesting
Make good cut flowers, cut blooms when mature.
Propagation
Division
It's easiest to start with division. Plant the divisions in the spring or autumn about 100 cm apart, depending on the how tall the type will be.
Seed
You can plant astilbe seeds, but they are short–lived and difficult to germinate.
