Vaccinium corymbosum, or the Northern Highbush Blueberry, is the most common commercially-grown species of Blueberry in North America. Blueberries are flowering shrubs that can be either deciduous or evergreen and are primarily grown for the fruit that gives the plant its name. Highbush species such as V. corymbosum are larger, while lowbush Blueberry species are smaller.
Blueberries are native to North America and eastern Asia. The shrubs typically grow anywhere from 1 to 6 feet in height, though unchecked, the Northern Highbush Blueberry can grow over 10 feet tall. This Blueberry species is native to the eastern U.S.
The health benefits of the Blueberry's fruit are well documented. Wild Blueberry species in particular are high in antioxidants, and are an excellent source of fiber and Vitamin C. Blueberries are frequently used in baked goods, jams, and yogurt.
Blueberry is usually grown from transplants rather than seed. Plant it in early spring in a location that offers full sun and rich, acidic, well-drained soil. Soak plant roots in water an hour before planting. Dig a hole twice the size of the root ball and backfill with soil and moist peat.
If you're planting highbush Blueberry, allow 4 to 6 feet between plants. If lowbush Blueberry, 3 to 4 feet should be sufficient. To increase fruit yield in later years, remove flowers from Blueberry plants the first two years after planting.
Blueberry can also be grown as an ornamental shrub. Along with its dark blue fruit, the shrub will display pink and white urn-shaped flowers in spring and orange, red, and yellow foliage in autumn.
