Black Raspberry (Rubus occidentalis)

Common in the Mountains, but scarce in the Piedmont and Coastal Plain of North Carolina, this prickly shrub is easily recognized by its glaucous stems and leaf undersides.

The fruits turn from red to black as they ripen and are quite delicious.

Black Raspberry (Rubus occidentalis)

Like other raspberries (subgenus Idaeobatus), the ripe fruit separates from the receptacle; with blackberries (subgenus Rubus), the receptacle breaks off with the fruit. Botanically speaking, the "berry" is an aggregate fruit composed of many drupelets.
