While The Arb is closed for the season, the online gift shop is open!  We plan to reopen to the public mid April. 

Please consider a membership, a donation or a purchase from the gift shop for holiday gift giving.  We appreciate our members, donors & visitors!


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.

New products added to our Bonfire Fundraiser!

It’s not too soon to start thinking about holiday gifts!  We have added additional products to our Bonfire Fundtraiser that feature the design drawn by The Arb Research Botanist Sheila Murray.  Tote bags, face masks, coffee mugs and a long sleeve t-shirt have been added to the collection.  A perfect gift for the plant lover in your life! 

The Arb receives a portion of the sale of each item in our Bonfire online store.
