Sour Cherry is a species of Prunus in the subgenus Cerasus (cherries), native to much of Europe and southwest Asia. It is closely related to the sweet cherry (Prunus avium), but has a fruit that is more acidic, and has greater nutritional benefits.The nutritional differences between the sweet and the tart or sour cherries are displayed at the general page for the fruit.
The tree is smaller than the sweet cherry (growing to a height of 4–10 m), 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. The reason for its popularity is its use in baking and recipe creation.including cherry pies, cherry desserts and other cherry-based recipes.
