Blueberries showing various stages of maturation. Blueberries are a widely distributed and widespread group of perennial flowering plants with blue or purple berries. They are classified in the section Cyanococcus within the genus Vaccinium. The genus Vaccinium has a mostly circumpolar distribution, with species mainly present in North America, Europe, and Asia. North American native species of blueberries are grown commercially in the Southern Hemisphere in Australia, New Zealand and South American nations. The Colombian or Andean blueberry, Vaccinium meridionale, is wild-harvested and commonly available locally.

Five species of blueberries grow wild in Canada, including Vaccinium myrtilloides, Vaccinium angustifolium and Vaccinium corymbosum, which grow on forest floors or near swamps. Wild blueberries reproduce by cross pollination, with each seed producing a plant with a different genetic composition, causing within the same species differences in growth, productivity, color, leaf characteristics, disease resistance, flavor, and other fruit characteristics. The flowers are bell-shaped, white, pale pink or red, sometimes tinged greenish. They are covered in a protective coating of powdery epicuticular wax, colloquially known as the “bloom”.
