Blueberry plants come in several varieties including Hi Bush, Low Bush, and Rabbiteye. Blueberries are easy to grow and can produce delicious fruit for many years. Blueberry bushes can produce berries by the second or third year. By the sixth year they can yield as much as two gallons of fruit per plant. The yield will continue to increase each year if the plants are given good care. Related to the rhododendron and azalea, blueberry bushes not only yield tasty berries but are also attractive, providing ornamental beauty with their scarlet autumn foliage and white spring flowers. Though they are tolerant of shade, higher yields are produced when grown in the sun. Blueberries thrive in acidic soil, ideally with a pH between 4 and 5.
Blueberry Plants come in several different varieties
Highbush Blueberries - Vaccinium corymbosum
Highbush Blueberries can reach heights of six to eight feet. They are hardy from Zones 4 to 7, and their berries are bigger and more abundant than berries from the Lowbush varieties. However, their flavor may be less intense and sweet.
Lowbush - Vaccinium angustifolium
Lowbush varieties are grown in colder regions of the US and are hardy from Zones 3 to 7. With flavorful sweet berries, Lowbush blueberries can grow up to two feet high and are spread by underground stems. Lowbush varieties do well in all well-drained soils. They can be used to create a lovely ornamental fruiting ground cover.
Rabbiteye - Vaccinium ashei
Hardy from Zones 7 to 10, the Rabbiteye blueberry grows up to nine feet high. Rabbiteye blueberry varieties are quite adaptable, and are productive and pest-tolerant. Mostly grown in the southeastern US, they require that two or more varieties be planted together to ensure pollination. Maintaining good soil moisture and mulching is also important because the feeder roots of the Rabbiteye are close to the surface and do not have root hairs.
