Plant Common Name

Beni-kawa Japanese Maple, Japanese Maple

General Description

The beautiful and ubiquitous Japanese maple is a small deciduous tree native to eastern Asia. Selected in about 1985 for its showy bark, which is even more brightly colored than that of 'Sango-kaku', 'Beni-kawa' has bright coral-red young stems which become duller as the branches age. The small, palmate (hand-shaped) leaves emerge pale green, deepen in color in summer, and turn yellow in fall. Clusters of red flowers dangle from the branches in spring, followed by small green two-winged fruits that mature to red-brown. This upright small tree is a lovely garden feature year round, especially in winter.

This maple does best in moist, humus-rich soil and sun to part shade. Use it as a featured specimen or bonsai plant. Its branches are especially striking against a white background.
