The Canada Red chokecherry grows to be about 20 to 30 feet tall at maturity. The mature spread of these plants is often a bit smaller at about 10 to 20 feet wide. Part of what makes this plant interesting from a visual perspective is that it can use one of a few forms to reach that mature size. While some Canada Red chokecherries have a multi-stemmed habit that makes them look more like large shrubs, others have a singular central trunk that gives a more tree-like look.
