Fullerton Arboretum

The Fullerton Arboretum is located on the northeast corner of the California State University in Fullerton, California, and contains a collection of plants from all over the globe. The Fullerton Arboretum is a 26-acre botanical garden that contains a collection of plants from all over the world. It is the largest botanical garden in Orange County, with a collection of more than 4,000 plants, making it the largest in the county. 

The Arboretum preserves species that are extinct or on the verge of extinction, and it also acts as a resource for agricultural history education. The Fullerton Arboretum was officially established in 1976 and opened its doors to the public in 1979. The Arboretum was previously a diseased orange grove, and has been restored into organic gardening plots as part of a larger restoration project. 


The Heritage House, built-in 1894 as the house and office of Dr. George C. Clark, one of Fullerton’s first physicians, is a focal point of the Arboretum. It is a National Historic Landmark. The house relocated to its current location amid the Arboretum in 1972. The renovated house currently functions as a museum dedicated to family life and medical practice in the 1890s.

The Arboretum’s garden trails wind through four primary collections: the Cultivated Collection, the Woodland Collection, the Mediterranean Collection, and the Desert Collection. Southern California natural vegetation, a Rare Fruit Grove, an 11,000 sq ft organic vegetable garden, historic citrus and avocado trees, a Channel Islands Garden, an extensive Cycad Collection, a Conifer Collection, a Palm Grove, community gardens, and a Children’s Garden are among the attractions.

The Arboretum provides people with the opportunity to both teach and learn about the environment and its preservation. They collaborate with students and teachers from a wide range of various campus departments to obtain information about the university. The findings of the research are dispersed throughout Orange County. They provide a variety of classes to the general public on topics ranging from bird watching to the protection of water resources. Students also work in the Heritage House, where they learn from exhibits and create art of their own.

Drs. David Walkington and Eugene Jones came up with the concept to establish an Arboretum on the northern portion of the Orange State College campus, which would later become known as California State University Fullerton. The property had previously been an orange grove, which was destroyed by a disease known as “rapid decline,” which caused the trees to die quickly. Teri Jones together, with other faculty wives, collaborated to garner support for the land’s development as an Arboretum. They were successful. The Arboretum Committee was formed and they later won a Disneyland Community Service Award for its environmental efforts.
