Tall (5 foot) deciduous, shrubby plant with very small, white flowers. Photographed at the edge of a pond in the midlands of South Carolina (Aiken County) at the Silver Bluff Audubon Center. This is a wild plant, but it may not be native. Fetterbush has been suggested as a possibility.
this is certainly a blueberry. My best guess as to which one is the highbush blueberry, Vaccinium corymbosum, but being immature [the leaves anyway] it could be a closely related species. I would say it is native. The rabbit-eye blueberry, Vaccinium ashei, a commercial species, is very similar in appearance.
