Box Elder Maple It has a thick trunk and upright branching habit, but is more often seen as a smaller tree with cane-like, bright green branches. These shade trees have brittle wood. Boxelder bugs eat seeds on female trees. The Box Elder Maple tree, Acer negundo, is also commonly known as ashleaf maple, Manitoba maple, box-elder maple, and western box-elder. Box Elder trees are fast growing and tolerate poor conditions. It can also tolerate flooding for extended periods (up to a month). The seeds are a source of food for birds and mammals, and are important because they stay on the tree through winter, when other food resources are scarce. The trunk is relatively short and tapering, and the crown is spreading and bushy. This deciduous maple tree is a small-to-medium-sized tree, reaching heights of 50 to 75 feet, with a trunk diameter up to 4 feet. Although it grows best on moist soils, box-elder is drought and cold resistant. |
