Cornus mas
The fruits of all dogwood species are drupes with one or two seeds, often brightly colorful. The drupes of species in the subgenus "Cornus" are edible. Many are without much flavor. "Cornus kousa" and "Cornus mas" are sold commercially as edible fruit trees. The fruits of "Cornus kousa" have a sweet, tropical pudding like flavor in addition to hard pits. The fruits of "Cornus mas" are both tart and sweet when completely ripe. They have been eaten in Eastern Europe for centuries, both as food and medicine to fight colds and flus. They are very high in vitamin C. However, those of species in subgenus "Swida" are mildly toxic to people, though readily eaten by birds.
