Vitis ×doaniana is endemic to well-drained soils of the Rolling Plains and Cross Timbers and Prairies regions in north central Texas and adjacent Oklahoma.
Vitis ×doaniana is a hybrid between V. mustangensis and V. acerifolia, and was once more common in nature than it is at present. It was named for Judge J. Doan of Wilbarger County, Texas, who manufactured wine from the berries of this species.
