Frequently Asked Questions

Fullerton Arboretum is not a park. It is more like a zoo or aquarium. It has many rare, threatened and endangered plants. It also features cultivated plants of historical significance, including a nationally recognized citrus collection. The arboretum nursery propagates many of these plants to make them available to institutions around the world and to the public.

Cal State Fullerton has supported and managed Fullerton Arboretum since 2020. The arboretum’s staff cares for its living and historic collections. The arboretum also relies on membership contributions, volunteers, events and donations to fund its programs, maintain operations and fulfill its mission.

Friends of Fullerton Arboretum is a group of dedicated volunteers that supports the arboretum’s staff with fundraising, education, plant sales and events at the arboretum.

The arboretum is free for all to explore and learn about plants, conservation and research. It relies on donations that can be made at the arboretum entrance or through its website.

The state of California requires that all public universities charge for parking on campus, which includes the spaces in front of the arboretum. Parking to visit the arboretum currently costs $4 per hour Monday through Friday, which can be paid through the ParkMobile app. Parking is free on weekends and university holidays.

The Visitor Information Center in Lot G, across from the Arboretum, is open from 8 a.m. to 4 p.m. Monday through Friday to assist guests with downloading and setting up the ParkMobile app on their smartphones. An alternative payment method may soon be available to guests without smartphones.
