Also known as the Box-elder, this is our only native maple that has divided leaves. These maples only grow to about 20 m but they grow quite quickly. Their range in Ontario is expanding as these maples can grow in a variety of soils and Manitoba Maples are often found in disturbed areas and along rivers and streams. They are known to have rather weak branches that tend to break during severe storms.
