Blueberry is a perennial fruit shrub in the Ericaceae family. Plants form multi-stemmed bushes with small, oval leaves that often display autumn colour, producing clusters of small white to pink bell-shaped flowers.
Fruit are small, round berries with blue-purple skin covered in a waxy bloom and sweet to mildly tart flesh. Berries are the edible part, consumed fresh, frozen, dried, or processed.
Cultivated in acidic, well-drained soils in cool to mild temperate climates, requiring specific pH conditions (4.2–5.5) for successful production. Notable for high antioxidant content and requirement for cross-pollination between compatible cultivars.
