Toona sinensis, with common names Chinese mahogany, Chinese toon, or red toon (Chinese: 香椿; Hindi: daaraluu; Malay: suren; Vietnamese: tông dù) is a species of Toona native to Asia.
The young leaves of T. sinensis are extensively used as a vegetable in China; they have a floral, yet onion-like flavor, attributed to volatile organosulfur compounds. 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 and for bodies of electric guitars.
Outside of its native region T.sinensis is valued more as a large ornamental tree for its haggard aspect. 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.
It is a deciduous tree growing to 25 metres (82 ft) tall with a trunk up to 70 cm diameter.
The leaves are pinnate, 50–70 cm long and 30–40 cm broad, with 10–40 leaflets, the terminal leaflet usually absent (paripinnate) but sometimes present (imparipennate); the individual leaflets 9–15 cm long and 2.5–4 cm broad, with an entire or weakly serrated margin.
The fruit is a capsule 2–3.5 cm long, containing several winged seeds.
