Japanese Sumac
BeginnerRhus chinensis
A small deciduous tree of the cashew family, recognized by the winged axis of its pinnate leaves. Grown as small bonsai for its vivid red autumn color and natural form.
About
Rhus chinensis, known in Japanese as nurude (白膠木) and in English as Chinese sumac, is a small deciduous tree in the cashew family (Anacardiaceae). It grows wild throughout Japan from Hokkaido to Okinawa and ranges across the Korean Peninsula, China and Southeast Asia to the Himalayas. A hardy pioneer, it is quick to colonize clearings and forest edges. The leaves are odd-pinnate, and the leaf axis between the leaflets carries a narrow wing, which distinguishes it from the similar-looking lacquer tree and wax tree. Plants are either male or female, and creamy white flowers open in large panicles in late summer. In autumn the foliage turns a vivid red, making it one of the signature trees of Japan's mountain autumn color. Galls formed on the leaves by aphids, called gobaishi, are rich in tannin and were once used for teeth blackening and dyeing. The name nurude is said to come from the white sap from a wounded trunk, which was used as a coating. Although it is related to the lacquer tree, it is considered much less irritating; sensitive people can still develop a rash, so wear gloves when pruning or repotting. As bonsai it is valued for its autumn color and rustic, natural form. Give it full sun and a free-draining mix. It grows quickly, so cut back extended shoots regularly to keep the shape. Repot every two to three years in spring before the buds open.
