The firm, medium to large, light blue berries of Blueberry ' Duke' have a mildly sweet flavour & retain their fresh quality longer than most varieties. ' Duke' blooms late, which protects the blossoms from the spring frost, but the berries then ripen early. The bushes are upright-growing, but the branches will droop to the ground when laden with fruit, often yielding over 20lbs per bush when mature. Supplied in 9cm pots.
