This shade intolerant shrub is found all over southern Ontario and was used for medicinal purposes by early settlers. It is important to note that all parts of the tree with the exception of the cherry flesh contain hydrocyanic acid, which is poisonous to humans. Since the Choke Cherry is quick to grow on exposed stream banks an land that has recently been logged, it helps to prevent erosion by stabilizing the soil. A wide variety of game and songbirds eat and disperse the chokecherries.

The leaves of the Choke Cherry range from 5-10 cm long with sharp teeth, they usually end in a hair-like point. The mature fruit hangs in clusters of 6-12 and each measure 8-12mm across. Photo by Jesse Wolf.

The bark of the Choke Cherry becomes darker with age and mature specimens are almost black. Lenticels are present, but not in horizontal patterns which is characteristic of most other species in the Prunus genus. Photo by Jesse Wolf.
