Vitis rupestris is a kind of grape native to the Southern and Western United States that is known by many common names including July, sand, sugar, beach, bush, currant, ingar, rock, and mountain grape. It is used for breeding several French-American hybrids as well as many root stocks. Rupestris St. George has been widely used in breeding and as a root stock and is perhaps the best known.
Vitis rupestris is a self-supporting bushy plant that does not grow in the shade, and was once found in well-drained prairie draws that collect water. Grazing has forced it into less grazed creek beds.
