As a 501(c)(3) nonprofit, Boyce Thompson Arboretum relies on admissions, donations, annual memberships, plant and merchandise sales and fundraising events to achieve our mission.
Volunteers support every operation and are the heart and soul of BTA. Major and Legacy Gifts have a long-term impact, providing support for buildings, gardens and large-scale programs.

Volunteer
There are many benefits to volunteering: you can take part in special projects and learn from professionals while you work together; you can be part of a close-knit community of volunteers; you can share your time, skills and talents with one of Arizona’s top natural attractions (and make a real difference!); and perhaps most importantly, you’ll have fun!

Did you know the Smith Greenhouses used to be the entrance to Boyce Thompson Arboretum?
When the Arboretum opened to the public in 1926, the historic Smith Greenhouses were the original entrance and Visitors Center. On the left is a photo of the east wing of the greenhouses from 1929. The right shows the east wing, present day.

Fall Color Update: Our canyon region is slowly turning gold. 🍂
The Jujube trees are currently putting on their full fall display along Thompson`s Trail, and the Honey Locust have begun to turn. The Chinese Pistache trees have yet to turn their vibrant reds and oranges, but are slowly changing as temperatures cool.
