See text Toona, commonly known as red cedar,[3] toon (also spelled tun) or toona, tooni (in Nepal and India) is a genus in the mahogany family, Meliaceae, native from Afghanistan south to India, and east to North Korea, Papua New Guinea and eastern Australia.

Toona sinensis is of interest as by far the most cold-tolerant species in the Meliaceae, native in China as far north as 40°N in the Beijing area, where its tender shoots, called xiangchun (Chinese: 香椿; pinyin: xiāngchūn), are a traditional local leaf vegetable.

It is the only member of the family that can be cultivated successfully in northern Europe, where it is sometimes planted as an ornamental tree in parks and avenues.

It provides a valuable hardwood used for furniture, ornamental panelling, shipbuilding, and musical instruments like the sitar, rudra veena, and drums.

Toona sinensis is used in Chinese traditional medicine and eaten as a vegetable or sauce in China (leaves and shoots).
