Grows from a low shrub to a 20ft tree, erect or straggling, dependent on moisture and site. It can form thickets and is often found in the understory in Aspen stands. Leaves are oval, often widest above the middle, with fine, sharp teeth. Western Chokecherry fruit is bright red to black juicy berries. It is bitter, but excellent for jelly with lots of added sugar.
