Astilbe chinensis foliage is deeply incised and it blooms in the late summer, it grows up to about 36″ tall. The flowers are usually pink, white, or red and attractive to butterflies.
Check Astilbe chinensis to ensure the soil is moist if not water, and water deeply rather than frequent spraying. Remember that clipping flower heads do not promote more flowers.
