Vitis girdiana is as species of wild grape known as the desert wild grape, coyote grape, or valley grape. It is native to southern California in the United States and to Baja California in Mexico. Vitis girdiana is a woody vine with a coating of woolly hairs, especially on new growth. The woolly leaves are heart-shaped to kidney-shaped with toothed edges and sometimes shallow lobes. The inflorescence is a panicle of unisexual flowers. The fruit is a spherical black grape usually not more than 8 millimeters wide. It grows in canyon and streambank habitat in hills and mountains of the region.

Where It Grows

Mexico*, North America, USA,

Cultivation

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.

Propagation

Seed is best sown in a cold frame as soon as it ripens. Six weeks of cold stratification improves germination rates, so stored seed should be sown in a cold frame as soon as it is obtained. Germination usually occurs in the first spring but may take another 12 months. Prick seedlings into individual pots when large enough to handle, overwinter in a cold frame, and plant out in early summer. Hardwood cuttings of the current season's growth can be taken in December or January and rooted in a frame. These may be 15–30cm long, or short single-bud sections about 5cm long. For the shorter sections, remove a thin strip of bark roughly 3cm long from the lower side to encourage callusing and rooting; these smaller cuttings need more protection than longer ones. Layering is also an option.

Other Uses

A yellow dye is obtained from fresh or dried leaves. The sap has been rubbed onto thinning or falling hair to promote healthy growth.

Notes

There are 60 to 70 species of Vitis.
