Vitis aestivalis

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 in 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 3rd node in a dense panicle 5–15 cm long. The fruit is a small grape 5–14 mm diameter, dark purple or black in color. It is the official state grape of Missouri. Summer grape prefers a drier upland habitat.
