History of Fullerton Arboretum
The Fullerton Arboretum was established on land that was originally an orange grove affected by a disease known as “quick decline,” which made it unsuitable for commercial citrus farming. In the early 1970s, Drs. David Walkington and Eugene Jones proposed transforming the grove into a botanical garden. In 1972, the Heritage House was moved to the site to preserve it from demolition. By 1976, the California State University Trustees approved the 26-acre project, and an architectural firm was commissioned to design the Arboretum. Construction began, and the Arboretum officially opened its doors in 1979.
