Vitis rupestris

Vitis rupestris is a species 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; it 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. Heavy use of grazing and herbicides have killed out much of the population. Vitis rupestris has been listed as threatened or endangered by Indiana, Kentucky, Pennsylvania, and Tennessee.[1] Known locations of wild Vitis rupestris are quickly disappearing, which may threaten the future of this grape species.[2]
