Acer negundo
(commonly known as Boxelder)Acer negundo, commonly known as Boxelder, is a tree native to Utah. The name boxelder is supposedly in reference to its use in making crates and boxes, and for its leaf similarity with those of elder (Sambucus).
Boxelder is a deciduous tree that has an irregular form due to its crooked limbs and uneven crown. It has a fast growth rate and a relatively short life span; it typically lives for 75 years. The height of boxelder greatly varies; full grown trees range anywhere from 25 feet to 70 feet high. The leaves of boxelder are divided, composed of three to seven leaflets that are from 2 to 4 inches long. Boxelder trees are dioecious with imperfect flowers. The plants flower from March to April, and produce samara type fruit from September to October. In addition, boxelder trees can produce asexually by sprouts that form on the stump or exposed roots.
Boxelder trees are host to boxelder bugs. These bugs are not harmful to the tree, but are a significant nuisance to homeowners by staining curtains with fecal matter.
Boxelder trees have a few widely known uses. They have been planted for erosion control because of their fibrous root system and resistance to drought and cold. Their seeds provide food to birds throughout the winter, and the sap has been used to a limited extent for making syrup.
