Duke’ is a highbush cultivar that typically grows 5-7’ tall. It flowers late but fruits early, often producing an abundant crop of blueberries. Waxy, bell-shaped, white flowers. Flowers are followed by medium to large, light blue blueberries which ripen in early season. Berries have a mildly sweet flavor. Ovate, dark green leaves (to 3.5” long) turn attractive shades of yellow and orange in fall.
