Vitis arizonica is a North American species of wild grape. It is a deciduous vine.

Common names for the grape are Arizona grape, canyon grape, and uva del monte.

Etymology

Vitis is Latin for "vine", while arizonica means "of or from Arizona".

Distribution

Arizona grape is found in California (Inyo County), Arizona, Nevada, New Mexico, western Texas, southern Utah, Sonora, Chihuahua, Coahuila, Durango, and Tamaulipas. Within Arizona, Vitis arizonica is found in all counties, except La Paz.

Morphology

Form: Vine 

General: Woody vine, sprawling or weakly climbing; stems generally 2–6 m long; the young twigs densely woolly, but losing this over time and the bark becoming shreddy. 

Leaves: Winter deciduous; broadly cordate, 3–10 cm long and about as wide, irregularly toothed and sometimes shallowly 3-lobed, more-or-less cottony hairy; petiole 1–3 cm long; tendrils opposite the leaves, bifurcate, lacking adhesive discs, withering quickly if not attached to something. 

Flowers: Inflorescence a loose, open, strongly branched panicle, 2–10 cm long, emerging opposite the leaves; flowers tiny with five, white petals. 

Fruits: Edible (but sometimes bitter) grapes, 8–10 mm thick, black.

The Arizona grape is a vigorously branching vine. Stems are slender, with significant tapering from base to apex. Fully developed leaves resemble a three-lobed heart shape and generally grow to an average of 4 inches long/wide. Leaves exhibit irregular toothed edge. Green flower buds develop in clusters, and small flowers bloom in a whitish green hue. Globe or ovate shaped fruit are typically 1/3-3/8 in diameter; immature fruit is green in color, developing into a deep purple or black. Fruit are clustered on red pedicels.

Uses

Vitis arizonica has been used in breeding varieties resistant to Pierce's Disease. Arizona grape is edible with different individual plants being sweet and others being bitter. The fruit can be used for wine making, jams, but is mainly consumed by wildlife.
