Family: Rhamnaceae
Common Name: Japanese Raisin Tree

There are only two species of trees in this genus from China and Japan, both of which are decid­uous. One is cultivated for its handsome foliage and sweet, edible fruit, formed by the base of the flower stem. The fruits are also used medic­inally and the timber is valued commercially.

Species

H. dulcis, Japanese raisin tree, is decid­uous and grows 10-15 m (33-50 ft) tall. The branches form an open, lacy effect and the broad leaves have finely serrated margins. These colour yellow in autumn. Cream flowers appear in early summer through to midsummer. The caramel brown fruits are formed from the thick­ened peduncle (flower stalk) and ripen in autumn to early winter. They are valued as confectionery in Japan.

Cultivation

These trees are best grown in a shel­tered position, in well-drained soil rich in organic matter. Pruning is generally unnecessary. Propagate from seed sown in spring or from semi-ripe cuttings in late summer to early autumn.
