The relatively slow-growing Chionanthus retusus is a small tree with a dense, round crown. Chionanthus retusus usually grows bushily for a long time, but will eventually grow into a small tree with a short trunk. The young twigs are brown and start to peel off after a few years. The old bark is beautifully cinnamon-brown and strongly flaking off and grooved black-brown. The oval, glossy dark green leaves are always opposite each other. In mild climates, the tree is semi-evergreen. The flowers open around midsummer. About 1.5 cm large, pure white flowers are gathered in compact panicles. The tree is dioecious and only the female plants can produce the dark blue fruits. Of course, the female flowers have to be pollinated by male ones. Fairly unknown, but perfectly hardy tree for use as a solitary or in small groups. C. retusus is fairly soil tolerant and tolerates lime. However, the soil must be nutritious and well-drained. It is a typical warmth lover and requires a place in full sun.
