It is a small deciduous tree with a short single trunk, with a dense crown reaching a height of about 8-12 m. The smooth bark is chestnut-brown, with prominent horizontal lenticels. The leaves are arranged alternately, simple, ovate-lanceolate, 5-13 cm long and 2.5-6.5 cm broad, with a short petiole and a serrate or doubly serrate margin. At the end of autumn, the green leaves turn yellow, red or crimson. The flowers are produced in racemose clusters of two to five together at nodes on short spurs in spring at the same time as the new leaves appear; they are white to pink, with five petals in the wild type tree. The fruit is a globose black drupe 8-10 mm diameter.
Cultivation and uses
It is widely grown as an ornamental tree, both in its native area and elsewhere throughout the temperate regions of the world. Numerous cultivars have been selected, many of them with double flowers with the stamens replaced by additional petals.
In cultivation in Europe and North America, it is usually grafted on to Prunus avium roots; the cultivated forms rarely bear fruit. It is viewed as part of the Japanese custom of Hanami.
