highbush blueberry

Name: highbush blueberry
Genus: Vaccinium
Species: corymbosum
Description: Blueberries are perennial flowering plants of the genus Vaccinium (a genus which also includes cranberries and bilberries) with dark-purple berries. The North American Vaccinium section Cyanococcus includes the ecologically and economically important blueberry species, Vaccinium corymbosum (highbush blueberry), Vaccinium angustifolium (lowbush blueberry), Vaccinium myrtilloides (velvet-leaf blueberry), and Vaccinium virgatum (rabbiteye blueberry), as well as at least nine other species of blueberry. Cyanococcus is found from northern Canada to Florida and as far west as Illinois and represents the most common fruits sold as "blueberries". They are usually erect but sometimes prostrate shrubs varying in size from 10 centimetres (3.9 in) to 4 metres (160 in) tall. In commercial blueberry production, smaller species are known as "lowbush blueberries" (synonymous with "wild"), and the larger species are known as "highbush blueberries". The leaves can be either deciduous or evergreen, ovate to lanceolate, and 1–8 centimetres (0.39–3.1 in) long and 0.5–3.5 centimetres (0.20–1.4 in) broad. The flowers are bell-shaped, white, pale pink or red, sometimes tinged greenish. The fruit is a berry 5–16 millimetres (0.20–0.63 in) diameter with a flared crown at the end; they are pale greenish at first, then reddish-purple, and finally indigo when ripe. They have a sweet taste when mature, with variable acidity. Blueberry bushes typically bear fruit in the middle of the growing season: fruiting times are affected by local conditions such as altitude and latitude, so the height of the crop can vary from May to August depending upon these conditions.
