The fruit is up to 3cm long[1], it contains 11.4% glucose, 4.7% fructose and 12.6% sucrose[7]. A sweet extract of the seed, boughs and young leaves is used as a substitute for honey[4]. The seed contains 15% protein and 7.8% fat[7].

Propagation

Seed - germinates freely if sown as soon as it is ripe in a cold frame[9]. Stored seed should be scarified and sown in early spring[12], it may not germinate for a year. Prick out the seedlings into individual pots when large enough to handle and grow on for at least their first winter in a greenhouse. Plant out in late spring after the last expected frosts and give some winter protection for their first couple of years outdoors.

Cuttings of half-ripe wood, July/August in a frame[9].

Cuttings of mature wood, late autumn in a frame[9].

Cultivation

Grows well in a fertile sandy loam in a sunny position[9].

Although the dormant plant is hardy to at least -15°c in Britain, it really prefers a continental climate to fully ripen its wood, it is then hardy to about -25°c[9]. The shoot tips are sometimes damaged by winter frosts in Britain[13] and the young growth in spring can also be damaged by late frosts[K]. The Japanese raisin tree is said to grow well in Cornwall[14], though our experience of this plant so far (1995) is that it is very difficult to establish. Perhaps older plants are as hardy as the reports above suggest, but younger plants are quite tender and often die in their first few winters outdoors[K]. The Japanese raisin tree is cultivated for its edible fruit in Japan.

The small white flowers are scented and are produced in terminal cymes[15].
