Blueberry 'Northsky' half-highbush produces small, sky blue berries. Fall leaf colour is red-maroon 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.
