Family: Vitaceae
Riverbank grape is a climbing vine commonly found along rivers, streams, swamps, and marshes in Ohio. It can climb up a tree as high as 50 feet. As it grows up into the canopy and creates shading with its own leaves, it can potentially kill its host plant.
Riverbank grape has green leaves that slightly resemble maple and sycamore leaves. The leaves are lobed with sharp edges. It is a flowering plant, and it produces small grapes in late summer that can be used to make jellies and wine. These grapes have so much pulp and seeds that it would take quite a few grapes to make a small amount of jelly.
