Additional Information

Vitis x 'Frontenac gris' is a vigorous grape vine that produces grayish-purple berries covered in a waxy bloom. The grapes can be eaten fresh or used in making white wine and desserts. Vitis are generally grown for fruit production, rather than for ornamental purposes. Provide a support for the vine to grow on and shelter from harsh winter winds. Regular training and pruning are required for optimum fruit production.
