Blueberries

Several blueberry species are indigenous to the United States. These include the lowbush blueberry (Vaccinium angustifolium), which is of commercial importance in Maine and Canada; the rabbiteye blueberry (V. ashei), which is grown commercially in the southern United States; and the highbush blueberry (V. corymbosum), which is the commercial blueberry of importance in Pennsylvania and in the Mid-Atlantic and Midwestern regions of the United States. The information that follows pertains solely to highbush blueberry production since this type of blueberry is of primary interest. Managing lowbush types in a home garden tends to be a challenge because the plants spread and form a dense mat. Rabbiteye blueberries can be grown in the extreme southeastern part of the state; their culture is similar to that described below for highbush production. Little information is available on performance of various rabbiteye varieties, however. Production of rabbiteye plants in cooler areas of the state has been very variable.
