Blackberry, is a perennial shrub in the family Rosaceae that is grown for its aggregate black fruit of the same name. The name blackberry is used to describe several species, including Rubus fruticosis (wild

blackberry), Rubus ursinus and Rubus argutus, two species native to North America. Blackberries have three stem types: erect, arching, and trailing. They often have thorns, but some varieties are thornless. The

leaves alternate along the stem with each group of leaves consisting of 3–5 leaflets. The leaves are prickly and bright green, and are toothed along the edges. The life-span of blackberry shrubs is variable, but

they usually live for less than ten years reaching heights of up to 3 m (10 ft). Blackberry may also be referred to as bramble and the shrubs grow native on every continent except Australia and Antarctica.
