Riverbank grape

Vitis riparia Michx, with common names riverbank grape or frost grape, is a vine indigenous to North America. As a climbing or trailing vine, it is widely distributed across central and eastern Canada and the central and northeastern parts of the United States, from Quebec to Texas, and eastern Montana to Nova Scotia. There are reports of isolated populations in the northwestern USA, but these are probably naturalized. It is long-lived and capable of reaching into the upper canopy of the tallest trees. It produces dark fruit that are appealing to both birds and people, and has been used extensively in commercial viticulture as grafted rootstock and in hybrid grape breeding programs.
