Vaccinium corymbosum 'Duke'
Vaccinium corymbosum is an upright, deciduous shrub native to eastern North America where it typically grows in moist woods, bogs, swamps and low areas. Blueberries grow best in acidic, medium to wet, well-drained organically rich soils in full sun to part shade. Fibrous roots need constant moisture and good drainage. Plants appreciate a good organic mulch. Although self-fertile, it is best to plant more than one variety, as cross-pollination produces larger berries and larger yields. ‘Duke’ is known for producing abundant deliciously tangy-sweet berries that often-times reach the size of quarters. Grown not just for fruit production, it is effective as a low hedge, in shrub borders or as part of less formal shrub plantings. Lovely bell-shaped white and pink-tinged flowers followed by large, light blue fruit, giving wat to vibrant orange and yellow fall foliage. Excellent for native plant gardens or open woodlands, also makes a great companion to rhododendrons and azaleas which share similar acidic soil requirements. Originates from Beltsville, Maryland, introduced in 1985.
