A Brief History of The Arboretum and Founder Frances McAllister

The gardens and buildings were the residence of The Arboretum’s founder, Frances McAllister, who first came to Flagstaff while she was passing through on the train in the 1930s. She was given a parcel of land in Flagstaff and a rustic cabin as a wedding gift by her husband John Vickers McAllister. Frances and her family traveled from Los Angeles every summer to spend time in their cabin with a marvelous vista of the San Francisco Peaks.

After her husband’s passing, Frances moved to Flagstaff permanently in 1967. She purchased the property that is the current site of The Arboretum and constructed a residence designed by the architect Walter Reichardt. Frances’ love of native plants began as a small child and she pursued her passion for gardening in her new home. She found that gardening at 7,000 feet is more challenging than in the temperate climate of L.A. She had more success with native species and adapted exotic plants from other high, dry locations. Her experimentations and success in gardening prompted her to want to share her gardens and research with the public.
