Prunus spinosa, called blackthorn or sloe, is an Old World species of flowering plant in the rose family, Rosaceae. It is locally naturalized in parts of the New World.
The fruits are used to make sloe gin in Britain and patxaran in Basque Country. The wood is used to make walking sticks, including the Irish shillelagh.
