The idea for the Fullerton Arboretum began to take root in the fall of 1970, initiated by Dr. David Walkington, Dr. Eugene Jones, and other faculty and students at California State College, Fullerton. The land, originally a diseased orange grove, was envisioned as a botanical garden. Community support was garnered through the efforts of faculty wives and the formation of the Arboretum Committee, which even earned a Disneyland Community Service Award for its environmental endeavors. In 1972, the California State University Trustees officially approved the botanical garden, and the Friends of Fullerton Arboretum organization was chartered to support fundraising and development. The historic Heritage House, built in 1894, was moved to the arboretum site in 1972, preserving a piece of local history. After years of planning and construction, the Fullerton Arboretum officially opened its doors to the public on October 21, 1979. In 2024, the venue was renamed the "Arboretum and Botanical Garden at Cal State Fullerton" to better reflect its comprehensive educational, research, and environmental mission.
