Cultivation and uses

The young leaves are extensively used as a vegetable in China; they have an onion-like flavour. The fruit, bark, and roots are used in traditional Chinese medicine for a wide variety of conditions. Plants with red young leaves are considered of better flavour than those where the young leaves are green.

The timber is hard and reddish; it is valuable, used for furniture making. It is by far the most cold-tolerant species in the Meliaceae and the only member of the family that can be cultivated successfully in northern Europe.
