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 <i>A. biternata</i>, 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 <i>A. japonica</i> versus white in <i>A. biternata</i>. There are many garden hybrids and cultivars involving several species of southeastern Asian <i>Astilbe</i> species.</p> |tables= |references={{Treatment/Reference |id=mellichamp1976a |text=Mellichamp, T.
