DistributionOccurs throughout the state, perhaps present in every county, but possibly absent from a few far eastern counties.

An Eastern species, ranging from southeastern Canada to southern FL and central TX. It is present in most counties from IL, MO, AR, and LA to the Atlantic Ocean.
AbundanceFrequent to common across the state, likely the most numerous and widespread grape species in NC, except for Muscadine (Muscadinia rotundifolia); certainly the most common grape in the Coastal Plain. Probably only infrequent in the far eastern counties north and south of Albemarle Sound.
HabitatThis is a species of mostly mesic forests and small openings, more so in uplands than in lowlands, even though many references say that it is found mostly in bottomland forests. It also occurs in upland thickets and on bluffs.
PhenologyBlooms from May to June, and fruits in September and October.
IdentificationAs with nearly all grapes, this is a high-climbing, woody, deciduous species. It has the standard large alternate leaves of a grape, typically about 6 inches across and long, with this species usually having three lobes, with a varying amount of depth of the sinuses between lobes. There are tendrils or an inflorescence opposite two of three leaves, but each third leaf does not have a tendril or inflorescence opposite it. There are several varieties, but all have considerable paleness below, and one or two of these are whitish below. Other Vitis species are green or greenish below. The fruits are in dangling clusters, with each berry being about 3/8-inch across.
Taxonomic CommentsThere are several varieties of this widespread species. Varieties aestivalis and bicolor (also named as argentifolia in some references) both occur in NC, with the latter restricted to the mountains.
