Vaccinium corymbosum
Summary
Vaccinium corymbosum, the northern highbush blueberry, is a North American species of blueberry which has become a food crop of significant economic importance. It is native to eastern Canada and the eastern and southern United States, from Ontario east to Nova Scotia and south as far as Florida and eastern Texas. It is also naturalized in other places: Europe, Japan, New Zealand, the Pacific Northwest of North America, etc. Other common names include blue huckleberry, tall huckleberry, swamp huckleberry, high blueberry, and swamp blueberry.
Vaccinium corymbosum is a deciduous shrub growing to tall and wide. It is often found in dense thickets. The dark glossy green leaves are elliptical and up to long. In autumn, the leaves turn to a brilliant red, orange, yellow, and/or purple.
The flowers are long bell- or urn-shaped white to very light pink, long.
The fruit is a diameter blue-black berry. This plant is found in wooded or open areas with moist acidic soils.
The species is tetraploid and does not self-pollinate. Most cultivars have a chilling requirement greater than 800 hours.
Many wild species of Vaccinium are thought to have been cultivated by Native Americans for thousands of years, with intentional crop burnings in northeastern areas being apparent from archeological evidence. V. corymbosum, being one of the species likely used by these peoples, was later studied and domesticated in 1908 by Elizabeth Coleman White and Frederick Vernon Coville.
In natural habitats, the berries are a food source for native and migrating birds, bears, and small mammals. The foliage is browsed by deer and rabbits.
The berries were collected and used in Native American cuisine in areas where Vaccinium corymbosum grew as a native plant.
Vaccinium corymbosum is the most common commercially grown blueberry in present-day North America.
It is also cultivated as an ornamental plant for home and wildlife gardens and natural landscaping projects. The pH must be very acidic (4.5 to 5.5).
