Distribution

Summer grape occurs throughout the eastern United States. The range of
the typical variety extends from southern Maine west through southern
Ontario to Wisconsin; south to Texas; and east to Florida [6,10,11,18].
Vitis aestivalis var. argentifolia generally occurs farther north and
inland than the typical variety; its range extends from New Hampshire
west to southern Minnesota and south to Kansas, Missouri, Alabama,
Tennessee, and Virginia [10,32]. Both varieties are uncommon at their
northern limits [20].
