Discussion

Vitis vinifera and cultivars formed by hybridization between it and native North American species or through selection are cultivated in Europe, many parts of the United States and southern Canada, and parts of Central and South America, Africa, Asia, and Australia; these have been reported persisting from cultivation (for example, in California, Utah, and Virginia) and occasionally escaping. Some specimens keying here may represent naturally occurring hybrids between native species and V. vinifera or its hybrid cultivars.

Vitis californica occurs in central and northern California (from San Luis Obispo to Inyo counties north) to southern Oregon. It is variable and intergrades with V. girdiana in southern California, and hybridizes with both V. girdiana and V. vinifera, often making identification difficult.
