- Description
-
Swamp highbush blueberry is a deciduous shrub in the Ericaceae (heath) family. It is native to the southeastern United States and is commercially important to the area.
Its native habitat includes bogs, swamps (especially blackwater, or at least away from strong alluvial influence), seepage, depression ponds (dolines), and other moist grounds. It will not grow in locations that include lime in the soil but will grow in, and prefers, very acidic soils. Best fruiting occurs when situated in full sun.
This plant has the tendency to sucker and, therefore, can form small colonies.
Propagating from seed is best done in a protected setting, such as a greenhouse. At this point, swamp highbush blueberry prefers a lightly shaded location and should be kept in this environment at least through its first winter. After that time, it can be planted outside in a location with protection from strong winds.
Sometimes confused with smooth highbush blueberry, swamp highbush blueberry (Vaccinium corymbosum) can be distinguished by its stems and leaf surfaces, which are pubescent with dingy hairs. It also has darker fruits that do not have a glaucous coating. It will have flowers that bloom earlier in the spring.
Insects, Diseases, and Other Plant Problems: No significant problems.
