Rubus pensilvanicus, also called Pennsylvania Blackberry or Wild Blackberry, is a thorny bramble native to Eastern North America. The canes are green at first but then turning dark red, usually ridged, with copious straight spines. The leaves are compound, usually bearing 5 or 7 leaflets. The flowers are white with large petals, bourne in mid-spring. The fruits are large aggregates of black drupelets, somewhat sweet and often used for jams and jellies.
