Food of the Day *Blueberry*

Blueberries are perennial flowering plants with indigo-colored berries from the section Cyanococcus within the genus Vaccinium (a genus that also includes cranberries and bilberries). Species in the section Cyanococcus are the most common^[1] fruits sold as "blueberries" and are native to North America (commercially cultivated highbush blueberries were not introduced into Europe until the 1930s).^[2]

Blueberries are usually erect. Prostrate shrubs can vary in size from 10 centimeters (3.9 in) to 4 meters (13 ft) in height. In the commercial production of blueberries, the smaller species are known as "low-bush blueberries" (synonymous with "wild"), while the larger species are known as "high-bush blueberries".

The leaves can be either deciduous or evergreen, ovate to lanceolate, and 1–8 cm (0.39–3.15 in) long and 0.5–3.5 cm (0.20–1.38 in) broad. The flowersare bell-shaped, white, pale pink or red, sometimes tinged greenish. The fruit is a berry 5–16 millimeters (0.20–0.63 in) in diameter with a flared crown at the end; they are pale greenish at first, then reddish-purple, and finally dark purple when ripe. They are covered in a protective coating of powderyepicuticular wax, colloquially knows as the "bloom".^[3] 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.
