Chinese toon is also known as: Chinese Mahogany, or Red Toon. Chinese toon is a fast growing deciduous tree, growing up to 25 m tall with a trunk up to 70 cm diameter. It is a source of valuable hardwood similar to mahagony. At the seedling stage the fresh young leaves and shoots are edible, highly nutritious, and a popular aromatic vegetable in China. Chinese toon shoots and leaves are excellent in stir fries, especially with egg, and for pickling and seasoning. The flavour resembles onions, with rich aromatic overtones. In China there is a large industry growing this ‘tree vegetable’ in greenhouses and tunnels year round. Also suitable for sprouts and microherb production. In Chinese medicine the fruit, bark, and leaves are used for diarrhea, dysentery, flatulence, and various other uses.
