One of about 30 American species or wild vines with the complete botanical name Vitis arizonica Engelm, first described around 1868. The German-American botanist Georg Engelmann (1809-1884) was honoured in its name. Trivial synonyms are Arizona Grape, Canyon Grape and Dawny Canyon Grape. The assumption that this is a natural hybrid has not been confirmed. The vine loves damp, permeable sandy soils and is found mainly in the southwest of the USA in the states of Arizona, Nevada, New Mexico, Texas and Utah, as well as in the north of Mexico. The small, dark blue berries are very popular with birds. The grapes were formerly used for grape jelly and grape juice, but also for wine. The vine is resistant to the vine disease Pierce Disease, which has been rampant in California since the 1980s. For this reason it was used in the new varieties Ambulo Blanc, Caminante Blanc, Camminare Noir, Errante Noir and Paseante Noir. See also under American vines and vine systematics.
