I'd like to give a quick plug to Bottoms Nursery in GA. They specialize in rabbiteye blueberries and SHB, and have some varieties that are hard to find elsewhere.
They also have a smaller selection of other fruit trees and shrubs.
I places an order of 4 blueberries and 1 fig with them and I was happy with the quality and selection for the price. A year later 3 out of the 4 blueberries I ordered are going strong, and the 1 fig I ordered is doing great! (I lost one blueberry due to transplant shock, which was entirely my fault due to planting too late in the season--the plant was very healthy when it arrived and I do not blame Bottoms Nursery in the slightest.)
