The Arboretum’s buildings and surrounding landscape were once home to our founder, Frances McAllister, who first came to Flagstaff while she was passing through on the train in the 1930s. A California native, she was given a parcel of land in Flagstaff and a rustic cabin as a wedding gift by her husband John Vickers McAllister, the McAllister Log House. Frances moved to Flagstaff permanently in 1967, after her husband died, and purchased the property that is the current site of The Arboretum. Her home, designed by the well-known architect Walter Reichardt, today is the Walter Reichardt Visitor’s Center.
The natural habitats and cultivated gardens at The Arboretum at Flagstaff showcase the diverse plants and plant communities of the Colorado Plateau's high-elevation regions.
