Common Name: Grape
Vitis saccharifera is a Deciduous Climber
It is harvested from the wild for local use as a food and source of materials.
E. Asia - C. and S. Japan.
We have very little information on this species and do not know if it will be hardy in Britain, though judging by its native range it could succeed outdoors in many parts of this country. The following notes are based on the general needs of the genus.
Prefers a deep rich moist well-drained moderately fertile loam[
]. Grows best in a calcareous soil[
]. Succeeds in sun or partial shade though a warm sunny position is required for the fruit to ripen[
Plants climb by means of tendrils[
Any pruning should be carried out in winter when the plants are dormant otherwise they bleed profusely[
Plants in this genus are notably susceptible to honey fungus[
Fruit - raw or dried for winter use[
]. The small fruit is black when it is fully mature[
Young leaves - chewed[
]. They can be wrapped around other foods and then baked, they impart a pleasant flavour.
Young tendrils - raw or cooked.
A yellow dye is obtained from the fresh or dried leaves[
Seed - best sown in a cold frame as soon as it is ripe[
]. 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.
