Blueberry 'Duke' highbush produces medium to large, firm, light blue fruits with a sweet and tangy flavor, perfect for fresh eating and baking. Fall leaf colour is orange-yellow and fruits ripen in the early season.

Blueberry plants grow best in a well-drained, acidic, moist, soil, in full sun or partial shade. Fruit size and production is improved when two or more cultivars are planted together. After fruiting, prune out any branches more than 4 years old, to ensure subsequent fruit production.
