All About The Gardens

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. 750 species of plants are found in our greenhouses, gardens, and natural habitats, all on 200 acres surrounded by the Coconino National Forest. The historic buildings at The Arb were once home to local philanthropist, Frances McAllister, who founded The Arb in 1981.
