Interior Boxelder: The Tough Native Tree That Thrives Where Others Give Up

If you’re looking for a no-fuss native tree that can handle whatever Mother Nature throws at it, meet the Interior Boxelder (Acer negundo var. interius). This hardy deciduous tree might not win any beauty contests, but it’s the reliable workhorse of the native plant world – and sometimes that’s exactly what your landscape needs.

What Exactly Is Interior Boxelder?

Interior Boxelder is a variety of the common boxelder maple, specifically adapted to the challenging conditions of North America’s interior regions. As a native perennial tree, it’s perfectly suited to the climate extremes found across much of the American West and Midwest. Don’t let the maple connection fool you – this tree has its own unique personality that sets it apart from its more famous cousins.

You might also encounter this tree listed under several scientific synonyms, including Acer interius, but regardless of what name it goes by, it’s the same tough-as-nails native species.

Where Does Interior Boxelder Call Home?

This adaptable tree is native to an impressive 18 states across the western and central United States, including Arizona, California, Colorado, Idaho, Kansas, Minnesota, Missouri, Montana, Nebraska, Nevada, New Mexico, North Dakota, Oklahoma, South Dakota, Utah, Washington, Wisconsin, and Wyoming. That’s quite a range, which tells you something important about this tree’s adaptability!
