Unique, lovely park tree that bears some resemblance to Ailanthus altissima. Grows vertically at first but later becomes broader. The smooth, brownish grey bark becomes grooved later. The twigs are a coppery green and have soft hair. When damaged, the bark and leaves give off an unpleasant odour. The imparipinnate leaves are 40 – 75 cm long and consist of 20 – 26 leaf segments. These are elongated, 8 - 13 cm in size, bare and glossy, dark green on top. The leaves are light green and hairy along the veins on the underside. Small, unpleasant-smelling white flowers appear in pendulous plumes up to 50 cm long. After flowering, a woody capsule with winged seeds develops. Toona sinensis only flowers during hot summers. 'Flamingo' is a lovely cultivar with leaves that are pink when they emerge. Toona sinensis has a brownish-grey bark that flakes off when the tree is older. The flaking platelets bend somewhat outwards. Bark and leaf give off an unpleasant smell when damaged.
Toona sinensis can eventually reach a height of 15 - 20 m, depending on the site and climate conditions.
Toona sinensis is average growing and can eventually reach a height of 15 - 20 m, depending on the site and climate conditions.
The right time to plant Toona sinensis is during the dormancy period. In Western Europe, Toona sinensis with root balls can generally be planted from mid-November to late April, although this depends strongly on the climatic conditions and the species of tree.
