- General Description
Blueberry is cultivated in North America and Europe for its edible fruits, which have been promoted as an antioxidant-containing 'superfood'.
Vaccinium corymbosum is cultivated in North America and West and Central Europe for its edible fruits, which are used to make pies, muffins, jams and syrups. It is a member of the heather, strawberry tree and rhododendron family (Ericaceae). There are about 500 species in the genus Vaccinium, including V. myrtillus (bilberry), V. oxycoccus (cranberry), V. macrocarpum (large American cranberry) and V. vitis-idaea (lingonberry or cowberry).
Vaccinium corymbosum was described by Swedish botanist Carl Linnaeus in 1753 from material collected by Peter Kalm in eastern North America. The generic name Vaccinium is from the Latin for blueberry and the specific epithet corymbosum refers to the umbrella-like inflorescences.

Geography and distribution
Vaccinium corymbosum is native to eastern USA and Canada, where it is found at up to 1,600 m above sea level.
It is cultivated in many countries, including the USA, Canada, Europe, Australia, New Zealand, South Africa, Mexico, Argentina, Uruguay and Chile.
Overview: An erect, deciduous shrub up to 1.5 m tall, sometimes producing suckers.
Leaves: Dark green, up to 7.0 × 2.5 cm, slightly leathery, sometimes with sharply toothed margins.
Flowers: Lantern-like (urceolate) with white or pink petals. Stamens (male parts) with hairy filaments.
Fruits: A berry, pale green, turning reddish-purple then dull blue-black on maturity, with a waxy blue-grey bloom, hairless, up to 12 mm in diameter.
Seeds: Viable seeds large, brown, up to 17 per fruit. Imperfect seeds small, pale, up to 38 per fruit.
Food and drink
Blueberry fruits are eaten raw, used to produce juice or processed into products including jams, syrups, pies, muffins, breakfast cereals and cereal bars.
Blueberries contain moderate levels of vitamin C, vitamin K, manganese and dietary fibre. They are promoted as a ‘superfood’, particularly in relation to their antioxidant properties.
Blueberries contain antioxidant anthocyanins, which have been alleged to increase communication between brain cells, and hence may have a role in preventing age-related memory-loss.
The fruits also contain ellagic acid, which is considered to be potentially effective against cancer.
Blueberry is also cultivated as an ornamental and makes a good container plant or border shrub. In addition to the attractive flowers and foliage of many cultivars, growers benefit from a harvest of edible fruits.
Mature blueberry seeds should be placed on top of a peat-sand (in equal parts) mixture and kept in a misting chamber. When the seed-leaves emerge, the pots should be moved to a greenhouse bench and watered daily.
Blueberry can be grown in acid soils (with a pH of 2.7–6.6) and tolerates low levels of nitrogen and phosphorus.
