Morren & Decaisne) A. Gray has been reported (1891 in Rhode Island, 1945 in New York) as spreading from cultivation; it probably has not naturalized. Aside from being much to the north of the range of A. biternata, it is much smaller, 15–80 cm tall; has cuneate-oblanceolate leaflets that are rarely lobed or cleft; and has perfect flowers with the petals longer than the stamens. Petals can be pink to purplish in A. japonica versus white in A. biternata. There are many garden hybrids and cultivars involving several species of southeastern Asian Astilbe species.</p> |tables= |references={{Treatment/Reference |id=mellichamp1976a |text=Mellichamp, T.
