Damson

The damson or damson plum (Prunus domestica subsp. insititia, or sometimes Prunus insititia), also archaically called the "damascene" is an edible drupaceous fruit, a subspecies of the plum tree. Varieties of insititia are found across Europe, but the name "damson" is derived from and most commonly applied to forms which are native to the United Kingdom. Damsons are relatively small plums with a distinctive, somewhat astringent taste, and are widely used for culinary purposes, particularly in fruit preserves.
