The Fullerton Arboretum is a fully qualified 501 (C) (3) non-profit organization. We rely on income from a variety of sources to sustain our operations and to build and support our infrastructure towards the future. This income comes from many sources, such as business operations through the Friends, membership revenue, occasional grants and special gifts and support from CSUF and the City of Fullerton.

However, one of the most significant aspects of our annual funding comes from individual donations and corporate/foundation giving. As a result of the many generous and much needed donations we received the last few years, the Arboretum has been able to finance the construction of the new Orange County Agricultural and Nikkei Heritage Museum, the new Potting Shed, our Channel Island Exhibit and other projects much needed.

Your gift to the Fullerton Arboretum is more than just a donation. It is an investment in the future of this beautiful sanctuary and it will help ensure the Arboretum will be here for generations to come so children can visit and learn about local history and the plant world—so adults can enjoy the diversity of plant life and learn more about the plant world around us plus it will remain a enjoyable place to visit for events and community activities.

Established in 1979, the Fullerton Arboretum has served the community as a premier resource for ecological, horticultural and historical education. The Arboretum is the largest botanical garden in Orange County. Encompassing 26 lush acres, The Fullerton Arboretum has assembled a permanent collection of over 4,000 unique and unusual plant species from around the world. With its ponds, streams and wildlife, the Fullerton Arboretum offers a tranquil retreat from a fast-paced urban life.

Consider the Fullerton Arboretum in your short and long-term philanthropic planning. It is one investment that literally lives on and grows as a result of your generosity. Read more about the various giving opportunities available at the Arboretum and thank you for your support.
