About Vitis cinerea (Engelm.) Millardet
Vitis cinerea, commonly called graybark grape, is a species of grape native to the United States. It is also known by the common names winter grape and possum grape. This grape produces small black berries that have a mildly unpleasant flavor for eating. It is plentiful in Missouri and Louisiana, and can also be found across the eastern half of the United States, ranging west to Texas, north to Illinois, and south to Florida. Its leaves are cordiform-emarginate, flabby, and dull in texture, with fine wrinkling between the secondary veins that resembles crepe paper. The leaf teeth are very blunt, and the buds are a gray-ashy violet color. Vitis cinerea grows in habitats including floodplain woodlands, wet thickets, and swampy forests.
