A prune is a dried fruit of various plum species, mostly Prunus domestica. It is wrinkly in shape, unlike its non-dried counterpart. More than 125 cultivars of plums are grown for drying. Four of the most common cultivars are French, Imperial, Italian, and Greengage. In general, prunes are freestone cultivars (the stone is easy to remove), whereas most other plums grown for fresh consumption are cling (the stone is more difficult to remove). Fresh prunes reach the market earlier than fresh plums and are usually smaller in size. Only some varieties of plum are usually called prunes when dried; others have usually been called "dried plums".
