Best grown in deep, loamy, humus-rich, medium moisture, well-drained soils in full sun. The more sun the sweeter the fruit. Tolerates a wide range of soil conditions, including average garden soils, but must have good drainage. Best sited in a location sheltered from winter winds (preferably a southern facing slope) and well removed from frost pockets. Young growth may be damaged in spring by late frosts. This grape is self-pollinating. For quality fruit production, it needs a support system, training, regular spraying and regular pruning to maximize fruit production. It can withstand the somewhat severe weather conditions in parts of the Eastern and Midwestern U.S. (cold winters followed by hot and humid summers) better than many other types of grape. Spreads by self-seeding. A number of wild animals and birds eat the fruits and help distribute the seeds to new locations.

For more detailed information on grape culture for the State of Missouri, see University of Missouri Extension publications on Home Fruit Production, Grape Culture (G6085) and Home Fruit Production Grape Training Systems (G6090), both of which are available for inspection at the Kemper Center Information Desk or on-line at Click on “Lawn and Gardening.”

‘Concord Seedless’ will not come true from seed, however, and is propagated asexually (cuttings and grafting).

Noteworthy Characteristics

Vitis labrusca, commonly known as fox grape, is a woody, deciduous vine that climbs by tendrils to 40’ long. It is native to woodlands and forest margins in eastern North America from Nova Scotia to Ontario south to Louisiana and Florida. It can climb to the tops of tall trees or sprawl horizontally over low-growing shrubs. Rough bark on mature trunks and stems shreds in strips. Bold-textured, oval-cordate, deep green leaves (each to 4-6” long) have appressed whitish to rusty brown woolly hairs on the undersides. Leaves vary in shape but typically have 3 palmate lobes. Each stem has one leaf per node, with tendrils or flowers located across from each leaf. Yellowish-green flowers (1/8” across) borne in compound racemes bloom in June on short, umbelliferous branches. Flowers have a sweet musky fragrance. Flowers give way to drooping clusters (to 8” long) of medium-sized, blue-black, edible grapes (each to 3/4” diameter) which ripen to dark purple in late mid-season. Grapes of this species are noted for having slipskins (skin easily slips off when a grape is squeezed) and a foxy smell and flavor (sweet earthy muskiness) as suggested by the common name of fox grape.

Genus name is the Latin name for the old world vineyard grape (Vitis vinifera).

Specific epithet comes from Latin meaning wild vine.

‘Concord Seedless’ is a seedless sport of the popular ‘Concord’ grape. In comparison to ‘Concord’, this seedless grape shares the distinctive sweet to sweet-tart flavor, but ripens about one week earlier and features smaller grape clusters with slightly smaller individual grapes. Occasionally a few seeds will appear, particularly in warm climates south of USDA Zone 6. This is a woody, deciduous, tendril-climbing vine that grows to 15-20’ long or more. Panicles of fragrant, greenish flowers in spring are followed by clusters of seedless grapes that ripen in late mid-season (late September in St. Louis). Large, shallowly-three-lobed, green foliage. It is considered to be an excellent grape for juices, jams, jellies and wine.


Grapes grown for fruit production are high maintenance plants that require regular chemical spraying and pruning. Grapes are susceptible to a large number of diseases, particularly in humid summer climates such as Missouri, including anthracnose, black rot, downy and powdery mildew, gray mold, crown gall and botrytis bunch rot. Insect pests include phylloxera, grape berry moth, Japanese beetle, leaf hopper, leaf roller, mealy bugs, spotted wing drosophila and flea beetles.


Grapes are primarily grown for fruit production in home fruit gardens where ornamental interest is not a concern. However, grapes do in fact have good ornamental value: bold summer foliage, some fall color, showy fruit and shaggy, twisted trunking and branching often best seen in winter. When grown on fences, walls, trellises, arbors or other structures, grapes can be quite attractive year-round and can provide good cover, screening, or shade to areas around the home.
