In 1924, the Boyce Thompson Arboretum (BTA) was founded by mining magnate William Boyce Thompson. The desert landscape inspired Boyce Thompson to create the arboretum with the mission of educating people about desert plants and their uses in an arid environment.
This mission continues today, and the Boyce Thompson Arboretum has grown in mission and size over its 100-year history. As an independent non-profit organization, the arboretum is in Superior, Arizona in the beautiful and stunning landscape of Picket post mountain and adjacent to the Tonto National Forest. The arboretum is located within 30 minutes of Mesa, AZ and 1 hour from downtown Phoenix.
At 372 acres, BTA is the largest and oldest botanical garden in the state of Arizona. BTA holds a collection of 4,030 taxa and 30,000 plants. The Arboretum grounds provide a collection of plants from all over the world’s varied desert and dry lands, displaying them alongside native Sonoran Desert vegetation. Wildlife is abundant and visitors enjoy well maintained hiking trails throughout the grounds.
It is not uncommon to see javelina, bobcat and a variety of native and migratory birds while working, hiking, and enjoying the grounds. BTA is an equal opportunity employer. We celebrate diversity and are committed to creating an inclusive environment for all employees.
