Blueberries are a confusing lot. They interbreed regularly so identification can be difficult. Vaccinium angustifolium and Vaccinium myrtilloides are the most common in this area. My trick to remembering which is which lies in their latin names. Angus- is a man’s name so he is bald and has little teeth at the edge of its leaves. Myrtill- is a woman’s name so she has hair but no teeth. The hair is not too obvious in this picture but are present and the leaves are smooth so this is V. myrtilloides.
