Astilbe Chinensis, or also known as tall false-buck’s-beard or Chinese Astilbe is herbaceous perennial. Astilbe Chinensis likes partial sun and moist clay soil added with some peat moss or sand. Too strong of a sun could burn them.
The 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 wather deeply rather than frequent spraying. Remember that clipping flower heads does not promote more flowers.
