Prunus americana is a shrub or small tree that can form small groves in moist middle elevation creekbeds and riparian areas. The small umbels of flowers bloom in the spring before the plant leafs out. The bark is gray and obviously peeling away in larger trunks. The trunks can be up to 21cm in diameter. The flowers are white and the petals are about one centimeter long. The leaves are serrate and mostly glabrous.

More or less frequent throughout the state. It prefers moist soil and is commonly found in open woodland along streams, about ponds and lakes, and in moist, prairie habitats. In Indiana this tree rarely reaches a diameter of 8 inches and is generally 2-5 inches in diameter. Its habit of sprouting prolifically gives rise to our "plum thickets."
