A species of Toona native to most of Southeast Asia, the Chinese Mahogany is a deciduous tree growing up to 25 m tall. Its great tolerance to cold makes it the only one in its family that can be cultivated successfully in European climates. A common substitute for the natively extinct Swietenia mahogany, the Chinese Mahogany’s hard, reddish timber is highly valuable and typically used in making furniture. In China, young leaves are used as a vegetable and noted for its onion-like taste. It is thought that the fruit, bark and roots of the tree are useful in improving male fertility, and is a common ingredient in Traditional Chinese Medicine.
