The American Plum is also sometimes known as the Wild Plum, Wild Yellow Plum or the Red Plum.
The leaves on the American Plum will grow as a fresh green color before turning red and pale yellow in autumn. The fruit of the American Plum will mature in August and September depending on your local climate. The 1" round plums are yellow and pale red as they develop, turning a deep red and purple color when mature. The American Plum will flower during the same time period that traditional Japanese Plums bloom. Since their pollen is compatible, they will pollinate each other and mutually increase each other's fruit production.
The American Plum forms a dense thicket with thorny branches when left to grow on its own. These thickets, along with highly desired fruit makes this a great choice for wildlife plantings. The roots of this shrub also hold soil in place, making it a wise choice for erosion control.
Fun Fact: The American Plum was widely used by Native Americans. The Cheyenne ate the plums and used its branches for the Sun Dance. The Navajo used the roots to make red dye.
