While research was the original primary focus of the Arboretum, over the years it has become known as a destination for local and out-of-town visitors who want to learn more about the native plants and animals found in northern Arizona, and as a wonderful venue for a wide variety of events and educational programs.

About the Arb

At 7,150 feet in elevation, The Arboretum at Flagstaff is a unique destination with a unique mission, specializing in plants native to the Colorado Plateau and northern Arizona. The Arboretum is home to 750 species of plants in greenhouses, gardens, and natural habitats--located on 200 acres deep within the Coconino National Forest. Once the home of founder and philanthropist Frances McAllister, The Arboretum today houses horticultural collections and rare plant specimens nestled among historic buildings in a natural setting.
