Vitis thunbergii
Propagation: Seed - best sown in a cold frame as soon as it is ripe[K]. Six weeks cold stratification improves the germination rate, and so stored seed is best sown in a cold frame as soon as it is obtained. Germination should take place in the first spring, but sometimes takes another 12 months. Prick out the seedlings into individual pots when they are large enough to handle and grow them on in a cold frame for their first winter. Plant out in early summer.
Cuttings of mature wood of the current seasons growth, December/January in a frame. These cuttings can be of wood 15 - 30cm long or they can be of short sections of the stem about 5cm long with just one bud at the top of the section. In this case a thin, narrow strip of the bark about 3cm long is removed from the bottom half of the side of the stem. This will encourage callusing and the formation of roots. Due to the size of these cuttings they need to be kept in a more protected environment than the longer cuttings.
Layering.
Cultivation: Prefers a deep rich moist well-drained moderately fertile loam[1][2]. Grows best in a calcareous soil[2]. Requires a position in full sun[2].
This species is a poor doer at Kew, it grows weakly and suffers lots of die-back[3].
Plants climb by means of tendrils[4].
Any pruning should be carried out in winter when the plants are dormant otherwise they bleed profusely[4][2].Requires a sheltered position[4].
Plants in this genus are notably susceptible to honey fungus[2].
Range: E. Asia - Japan, Korea.
Habitat: Thickets in hills and mountains all over Japan[5].
Edibility: Fruit - raw or dried for winter use[6][7][8]. The fruit is about 9mm in diameter[2] and is borne in bunches.
Young leaves - cooked[6]. The young leaves are also wrapped around other foods and then baked, they impart a pleasant flavour.
Young tendrils - raw or cooked.
Usage: A yellow dye is obtained from the fresh or dried leaves[9].
Pollinators: Insects
Soil: Can grow in light, medium, and heavy soils.
