These large, juicy-sweet, blue-black berries grow abundantly for five of your summer's sweetest weeks. Enjoy the firm, nutritious berries as a snack or instant dessert; and they're superb in a pie, mousse or sorbet. The thornless blackberry plants are upright, orderly and easy to maintain. Growing 4-8', the plants form a sturdy hedge with the canes supporting pounds of fruit without a trellis.
