The blackberry is a berry made by any of several species in the "Rubus" genus of the "Rosaceae" family. The blackberry shrub is called "bramble" in Britain, but in the western U.S. "caneberry" is the term used for both blackberries and raspberries.

It is a widespread and well known group of over 375 species which reproduce by apomixis. They are native all over the temperate Northern hemisphere and South America. The blackberry grows to about 3 m (9 ft) in height. It makes an edible black fruit, known by the same name. The plant tolerates poor soil very well.

The plant down its strong suckering roots amongst garden hedges and shrubs. It will grow fast, taking over uncultivated spots very quickly. In some parts of the world, such as in Australia, Chile, New Zealand, and the Pacific Northwest of North America, some blackberry species are regarded as weeds.

What distinguishes the blackberry from its raspberry relatives is whether or not the torus (receptacle or stem) "picks with" (i.e., stays with) the fruit. When picking a blackberry fruit, the torus stays with the fruit. With a raspberry, the torus remains on the plant, leaving a hollow core in the raspberry fruit.
