Vitis aestivalis, the summer grape, or pigeon grape is a species of grape native to eastern North America from southern Ontario east to Maine, west to Oklahoma, and south to Florida and Texas. It is a vigorous vine, growing to 10 m or more high on trees. The leaves are 7–20 cm long, suborbicular, and usually a little broader than long; they are variable in shape, from unlobed to deeply three- or five-lobed, green above, and densely hairy below. The flowers are produced at every third node in a dense panicle 5–15 cm long. The fruit is a small grape 5–14 mm diameter, dark purple or black in colour. It is the official state grape of Missouri. Summer grape prefers a drier upland habitat. The four varieties are: V. a. var. aestivalis V. a. var. bicolor Deam (syn. var. argentifolia Fernald; Silverleaf Grape), formerly called Vitis bicolor, but now considered a northern variation of Vitis aestivalis, native range is in the Northeastern United States and parts of Southern Ontario V. a. var. lincecumii (Buckley) Munson V. a. var. bourquiniana L.H. Bailey, native to the south, sometimes called Vitis bourquiniana, has tomentose undersides to the leaves
