A cultivar of a native, this boxelder stays under 30 feet with an outstanding display of chartreuse yellow leaves. It can take wet feet and once established can also withstand some drought. Boxelder is relatively fast growing, therefore has weaker branching and can suffer damage from ice or heavy snow.
