Nectarberry Blackberry

Nectarberry (Rubus sp.) produces very large berries, twice the size of blackberries, that grow on a thorny bush. The berries are 1 1/2 inches (4 cm) long by 1 inch (2.5 cm) wide, with a dull, reddish-black skin. There are few seeds inside. Nectarberries are soft, fragrant and sweet with some tartness.

They ripen in June and are cold hardy to USDA Zone 6
