The lowbush blueberry grows to one foot (30 cm) high. It is found primarily in New Hampshire and New York. The highbush blueberry is found in swamps from Nova Scotia south to Georgia. It is distinguished by its clusters of small, urn-shaped white flowers. The leaves are smooth above and hairy beneath. The highbush blueberry grows to 15 feet (4.5 m) high. It is the main source of commercially grown blueberries. Cultivated highbush blueberries are also grown in the Midwest and on the West Coast. The rabbiteye blueberry, found in Georgia, Florida, and Alabama, is also an important commercial shrub. It ranges in height from 4 to 18 feet (1.2 to 5.5 m). The rabbiteye blueberry has pale pink flowers with white or red markings.

Blueberries have been a popular fruit in the United States and Canada since the 1800's. They are eaten fresh and canned, and are used in pies, muffins, and breads. Both cultivated and wild blueberries are harvested.
