Grapes, Black 'Concord Seedless' (Live Plant)

Key Characteristics

• Origin: 'Concord Seedless' is a seedless variant of the classic 'Concord' grape (Vitis labrusca), which was developed in 1849 by Ephraim Wales Bull in Concord, Massachusetts. 'Concord Seedless' retains many of the desirable characteristics of the original Concord but without the seeds. The exact origin and selection history of the seedless version can vary depending on the source, but it is a popular mutation or subsequent breeding of the original Concord.
• Patent Status: Given that the original 'Concord' is not patented and 'Concord Seedless' has been available for a significant period, many strains are likely **not currently under active patent**. It's always best to check with the specific nursery or supplier for confirmation if patent status is a concern for commercial propagation.
• Berry Production: Produces medium-sized, round, blue-black "slip-skin" berries, similar in appearance and flavor to seeded Concord grapes but without the hard seeds. The flesh is juicy and has the characteristic sweet and slightly tart "foxy" flavor of Concord grapes. Clusters are typically medium-sized and can be abundant.
• Ripening Time: Ripens in the **mid to late season**, typically in September, around the same time or sometimes slightly earlier (up to a week) than traditional seeded Concord grapes.
• Plant Size and Appearance: 'Concord Seedless' is a vigorous, hardy grapevine with a growth habit similar to the standard Concord. It is a deciduous, woody vine that requires a trellis or other support.
• Flowers: Produces typical, inconspicuous grapevine flowers in the spring. It is self-pollinating.
• Hardiness: Generally very hardy, similar to the standard Concord, and suitable for USDA Zones **4 through 9**. It is well-adapted to colder climates.
• Pollination: 'Concord Seedless' is **self-fertile** and does not require another grape variety for pollination to produce fruit.
• Growing Conditions:
  • Sunlight: Requires full sun (at least 6-8 hours of direct sunlight) for optimal growth, fruit production, and flavor.
  • Soil: Prefers well-drained soil but is adaptable to various soil types.
  • Watering: Requires consistent moisture, especially during the growing season and fruit development. Grapes are drought-resistant once established.
  • Fertilizing: Apply a balanced fertilizer in early spring. Avoid excessive nitrogen.
  • Pruning: Requires regular pruning during the dormant season to establish the vine structure and maintain productivity. Spur pruning or cane pruning can be used.
• Uses: Primarily grown as a **table grape** for:
  • Fresh eating, appealing to those who prefer seedless grapes.
  • Making juice with the classic Concord flavor but without seeds.
  • Producing seedless jelly and jams.
  • Suitable for pies and other baked goods where seedless fruit is desired.
• Wildlife Value: Grapevines can provide shelter and food for various wildlife, particularly birds that may consume the grapes.
• Ornamental Value: Grapevines can be attractive when trained on arbors, pergolas, or fences, providing shade and visual interest. The foliage turns yellow in the fall.
• Disease and Pest Resistance: Similar to the standard Concord, 'Concord Seedless' is generally considered to have good disease resistance to many common grape ailments, though it can be susceptible to powdery mildew and other fungal diseases under certain conditions.
