Dwarf cherry

''Prunus cerasus'' is a species of ''Prunus'' in the subgenus ''Cerasus'' , native to much of Europe and southwest Asia. It is closely related to the sweet cherry , but has a fruit that is more acidic.

The tree is smaller than the sweet cherry , has twiggy branches, and its crimson-to-near-black cherries are borne upon shorter stalks. There are several varieties of the sour cherry: the dark-red morello cherry and the lighter-red varieties including the amarelle cherry, and the popular Montmorency cherry.

The Montmorency cherry is the most popular type of sour cherry in America. The reason for its popularity is its use in baking and recipe creation. including cherry pies, cherry desserts and other cherry-based recipes.
