A single tree can produce an abundance of fruit. Home gardeners and homesteaders will enjoy eating the plums fresh or cooking with them. For preservation, plums can be canned, made into jam, or dehydrated into prunes. The skin of the plum is thin, and its yellow flesh clings tightly to the pit. Plums are good sources of fiber and high in vitamins A, C, and K. Due to its dark red coloring, the Santa Rosa plum is high in the antioxidants known as anthocyanins.
