Please help ID shrub w/berries
Tall shrub, with bluish-black berries ripening same time as blueberries & huckleberries. Well-drained woodland edge in Massachusetts, Zone 6. Leaves 5-6 cm (not mm as on photo), and berries about 8mm.
Is this a wild highbush blueberry? Or something else, and in that case, are the berries edible?
