Rubus fruticosus

Also known as blackberry, the bramble is a sprawling shrub, with scrambling stems that are covered with viscious thorns. These stems can arch to the ground and take root to form new plants. The rose-like flowers tend to be creamy white but can also be deep pink to purple. The unmistakable blackberries are a deep purplish-black when ripe and are formed of segments called drupelets.
