Ericaceae

Vaccinium corymbosum ‘Polaris’ is a hardy, semi-dwarf blueberry bush, particularly suited to cold climates. This deciduous shrub develops a compact habit, slightly wider than tall, ideal for small gardens, edible borders, and container growing. In spring, pinkish-white bell-shaped flowers attract pollinators and announce an early summer harvest. The large blueberries are firm, sweet, and very aromatic. Its dark green foliage turns beautiful bright red hues in autumn, adding significant ornamental interest. Vaccinium corymbosum ‘Polaris’ requires acidic soil, rich in organic matter, and well-drained, as well as a sunny exposure to optimize fruit production in northern climates.
