Vitis arizonica

It is a native deciduous vine found in the southwestern United States that produces small, purple-black grapes. It grows in canyons and riparian areas, tolerates drought and cold, and is a food source for wildlife. The plant has heart-shaped leaves and produces tiny, greenish-white flowers in the spring. 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 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. Inflorescence a loose, open, strongly branched panicle, 2–10 cm long, emerging opposite the leaves; flowers tiny with five, white petals.
