The Arboretum at Flagstaff is a 200-acre botanical garden and research facility located at 7,150 feet elevation in northern Arizona’s ponderosa pine forest. Established in 1981, it specializes in high-altitude native plants of the Colorado Plateau, maintaining living collections of over 750 species of plants, with a particular focus on rare, threatened, and endangered flora of the region. The facility includes demonstration gardens, greenhouses, research plots, and natural areas that showcase native wildflowers, grasses, trees and shrubs adapted to the challenging climate of high-elevation environments.

The Arboretum conducts significant research in plant conservation, including seed banking, rare plant monitoring, and habitat restoration projects. It serves as both a public garden and a scientific institution, offering educational programs and maintaining partnerships with federal agencies and other conservation organizations to protect the botanical heritage of the Colorado Plateau. Since I try to be accurate but may make mistakes with very specific details like this, you may want to verify any particular numbers or dates I’ve mentioned.
