The plant prefers moist, well-drained soil and partial shade. It is native to Japan. The foliage is generally green but some cultivars have bronze or reddish tints.
Companion planting
Astilbe thunbergii thrives in partial shade and moist soil, making it a good companion plant for other shade-loving perennials such as hostas, ferns, and heucheras.
