Other info. - THis is a common Missouri species. I have encountered areas where this plant is much more abundant than any of its grape relatives, genus Vitis, and has climbed to the very top of some very tall trees (20-30m). This species does produce a grape-like fruit but it is not edible. The easiest way to distinguish between this species and the true grapes is to notice that the flower clusters of this species are compact and broad. Grapes have clusters which are elongated.
