Prefers semi-shaded sites will tolerate more light if the soil is kept moist.
Moisture
Needs moist soil. Plants growing in dry conditions will be small, few blooms and tend to dry up during the hotter days in the summer. The astilbe chinensis tend to be a bit more forgiving when it comes to drier conditions
Soil & Site
rich, humusy moist well-drained soils
Flowers
plumes of white florets
Leaves
ternately compound, leaflets are coarsely serrated, dissected foliage is an attractive feature of the plant
Dimensions
20-25 inches tall
Maintenance
Division of the clumps every 2-3 years will help to maintain the vigor of the plant. Astilbe are heavy feeders and need to be fertilized every year in the spring and also in the early fall. Some of my Astilbe tend to heave in the winter. In the spring I cover the exposed roots with soil, mulch or dug them in. Be careful since many Astilbe are easily pulled out of the soil.
Propagation
division in the spring, most cultivars will not come true from seed
