Experience the lush beauty of the Arizona Upland Sonoran Desert at the state's oldest and largest botanical garden. With spectacular views of Picketpost Mountain, Boyce Thompson Arboretum is located in scenic Queen Creek Canyon, just 30 minutes from Mesa, Arizona. Featuring plant collections from the world’s deserts, historic buildings and hidden gardens along miles of trails, the Arboretum is on the National Register of Historic Places. A haven for wildlife, the Arboretum has been called "the most enchanting" Audubon Important Birding Area in Arizona.

Boyce Thompson Arboretum was founded in 1924 by William Boyce Thompson, a mining magnate who understood the importance of plants as the ultimate source of our survival and well-being. That legacy continues today as the Arboretum offers tours, classes and events, bringing a wide community together in appreciation of the astounding diversity of its growing collection.
