|Prunus pensylvanica is a small tree with a spreading, branching pattern, forming a rounded crown. Height is 25 to 40 feet tall, spread 18 to 25 feet. It has alternate, simple, ovate leaves. The leaves are deep green and lustrous throughout the summer, yellow and red in fall. Small white flowers in clusters of 2 to 5 form umbels or short racemes, blooming in late spring or early summer. Small, red, sour cherries are produced in the summer.
This is a pioneer species in cut-over forest lands, requiring full sun. Once a canopy develops it yields to other species, being shade
intolerant. Native from Labrador to British Columbia, down to North Carolina and Colorado. Introduced 1773.
