Duke is known both for its early season fruit, which is large with a firm, crisp texture, and its high yield of berries. The fruit has a tangy, sweet, delicate flavor. This blueberry bush is an attractive plant with white, pink-tinged flowers in the spring; large, light blue berries in the summer; and vibrant yellow and orange fall foliage. It is a great plant to use for landscape design, as well as in the garden or berry patch. This bush can grow up to six feet tall at maturity. While self-pollinating, this variety benefits from cross-pollination with other cultivars, producing even larger yields.
