Delma is a seedling damson, discovered growing in a garden in southern England. Like most damsons it is primarily a culinary fruit but can also be eaten fresh when fully ripe - it is one of the sweeter-tasting damsons.

Delma is similar in most respects to the well known traditional Shropshire Prune damson, but has the sweetness typical of Blue Violet.
