The Marquis Grape, 'Vitis 'Marquis', is a mid-season, white seedless grape with large, round berries borne in large clusters. It has excellent flavor, good cold hardiness, and is a great choice for home gardens. Flowers of Marquis are perfect, self-fertile, and bloom in mid-season. The skin is thick, flesh is melting and very juicy and the seed traces are medium in size and soft. The skin softens as the berries continue to ripen. Foliage and fruit are moderately susceptible to powdery mildew, downy mildew, and black rot. This vigorous grower produces abundant crops early-to-late September. Eat them off the vine or use them for cooking in jellies, jams and desserts. This grape tolerates a wide range of soil conditions, but must have good drainage. Grapes are primarily grown for fruit production in home fruit gardens where they provide good ornamental value: bold summer foliage, showy fruit, some fall color and shaggy, twisted trunking and branching often best seen in winter. Grapes need a good support system like fences, walls, trellises, arbors or other structures. The grape vines can be quite attractive year-round and can provide good cover, screening, or shade to areas around the home. Grapes need full sunlight and high temperatures to ripen, so plant on southern slopes, the south side of windbreaks, or the south sides of buildings. Considered to be a good grape for juices and jellies. Birds love grapes, so be sure to plant some to share.
