Plums are medium-sized fruits, measuring an average of 4 centimeters in diameter, with deep red to maroon-colored skin. The plump plums are very round and slightly heart-shaped with the characteristic vertical suture running from stem to end. They have a firm, blood red flesh with a crisp, juicy texture.
Plums are a good source of vitamins C, K, and A, copper, and dietary fiber. They are also a source of B-complex vitamins, including folate, potassium and the minerals manganese, magnesium, fluoride, phosphorus and iron.
