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.
