Plant Common Name

Concord Grape, Fox Grape

General Description

Renowned for its delicious deep-blue fruits that are widely used for commercial jam and juice, Concord grape is a selection of Vitis labrusca, a hardy, deciduous, woody vine native to eastern North America. It produces numerous bunches of firm, large, seeded grapes in late summer, midway in the grape season. The fruits are "slipskin", with the outer skin freely slipping off the juicy inner flesh. Their scent and flavor are often described as having a "foxy" quality. Fragrant, inconspicuous flowers precede the fruits in early summer. The attractive, lobed, rich green leaves turn burnished shades of orange and gold in fall.

Vigorous and tough, extremely cold hardy, and producing well even in short growing seasons, Concord grape requires less summer heat and more winter cold than European grape varieties. It needs full sun for best fruiting and excels in average to highly fertile soil that is well-drained. This vine grows fast enough to cover an arch, arbor or walkway in one season. Plants must be pruned in mid- to late winter when dormant to maximize fruit production the following growing season. In regions with cold winters and short growing seasons, the vine may persist for years, but fruits often don't fully ripen before the onset of fall frosts.
