Vaccinium corymbosum ‘Duke’, commonly known as Duke Highbush Blueberry, is a productive, early-season blueberry variety prized for its abundant clusters of large, firm blueberries, attractive spring flowers, and excellent cold hardiness. This reliable cultivar is an excellent choice for home gardens, edible landscapes, berry gardens, and wildlife-friendly plantings.
In spring, Vaccinium corymbosum ‘Duke’ produces clusters of delicate, bell-shaped white flowers that attract bees and other beneficial pollinators. The flowers are followed by heavy crops of large, light blue berries that ripen early in the blueberry season. The firm, flavorful fruit is excellent for fresh eating and can also be used in baking, smoothies, jams, preserves, and other culinary preparations.
Duke Highbush Blueberry performs best in full sun and requires moist, well-drained, acidic soil rich in organic matter. Consistent soil moisture is especially important during flowering and fruit development. Although ‘Duke’ can produce fruit on its own, planting multiple compatible highbush blueberry varieties can improve pollination and increase overall fruit production.
In addition to its edible fruit, Vaccinium corymbosum ‘Duke’ provides ornamental value throughout the year. Its green foliage develops attractive shades of yellow, orange, and red in fall, while its upright, well-branched growth habit provides structure in edible and ornamental landscapes.
With its early ripening season, large firm berries, attractive spring flowers, fall color, and pollinator-friendly blooms, Vaccinium corymbosum ‘Duke’ is an excellent highbush blueberry variety for gardeners looking to enjoy an abundant harvest of fresh, homegrown fruit.
