What is Bramble?

Brambles are thorny plants of the genus Rubus, in the rose family (Rosaceae). Bramble fruit is the fruit of any such plant, including the blackberry and raspberry. The word comes from Germanic *bram-bezi, whence also German Brombeere and French framboise. In popular UK usage the term primarily refers to the blackberry bush; in Scotland and the north of England it refers to both the blackberry bush and its fruits.

Bramble bushes have a distinctive growth form. They send up long, arching canes that do not flower or set fruit until the second year of growth. Many types of brambles bear edible fruit, and many have recurved thorns that dig into clothing and flesh when the victim tries to pull away from them. Some types also have hair-like thorns. Brambles usually have trifoliate or palmately-compound leaves.

Bramble fruits are aggregate fruits. Each small unit is called a drupelet. In some, such as blackberry, the flower receptacle is elongate and part of the ripe fruit, making the blackberry an aggregate-accessory fruit.
