Astilbe

Astilbe arendsii

Easily grown in average, medium, well-drained soils in part shade to full shade. Prefers moist, humusy, organically rich soils. Soils should not be allowed to dry out. If regularly watered, foliage will usually remain attractive throughout the growing season. A summer compost mulch helps retain soil moisture. Removing faded flower stalks will not prolong bloom, but may improve plant appearance, particularly if a ground cover look is desired.  

Growing Conditions

Height 12 to 24 inches
Light Requirements Part shade to full shade
Bloom time July
Zone 3 to 8

Additional Info

the Arendsii hybrids have little if any drought tolerance

Divide when clumps become overcrowded (every 3-4 years)

Foliage decline (leaves brown up), sometimes with significant dieback, will often occur in hot summers
