USDA Symbol: acne2
USDA Native Status:
Ash-leaf maple or box elder is usually a small to medium-sized tree, 35-50 ft. tall, commonly with a short trunk and widely spreading branches and light green foliage. It doesn’t look like other maples because of its irregular growth, sprouting base, and compound leaves. Fall foliage is usually insignificant.
Box Elder is classed with maples, having similar, paired key fruits, but is easily distinguishable by the pinnately compound leaves. Hardy and fast-growing, it is planted for shade and shelterbelts but is short-lived and easily broken in storms. Common and widely distributed, it is spreading in the East as a weed tree. The common name indicates the resemblance of the foliage to that of elders (Sambucus) and the whitish wood to that of Box (Buxus sempervirens L.).

Conditions Comments: Ash-leaf maple or box elder is usually a small to medium-sized tree, commonly with a short trunk and widely spreading branches and light green foliage. It doesnt look like other maples because of its irregular growth, sprouting base, and compound leaves. Fall foliage is usually insignificant.
BenefitUse Ornamental: This hardy, fast-growing tree can survive dry and extremely cold conditions, so it is widely planted as a shade and shelterbelt tree.
Use Wildlife: Birds, Other Showy Insects
Use Food: Plains Indians made sugar from the sap. When sugar was scarce, Prairie settlers sometimes tapped this tree to make maple syrup, but Manitoba maple is the least productive maple for this purpose.
Warning: The wood is weak and will break up in ice and wind.
Conspicuous Flowers: yes
