Fullerton Arboretum is a 26-acre botanical garden that serves students, faculty and the broader community as an urban oasis, an outdoor laboratory for research and environmental education, and a steward of worldwide plant conservation and regional agricultural heritage. As one of only three arboreta in California accredited at the highest level by ArbNet — an international program recognizing an arboretum’s professionalism and capacity for scientific and conservation-related collaboration — Fullerton Arboretum is home to rare and endangered species, historically significant cultivars and a nationally recognized citrus collection. We seek your support to enhance our collection work; increase opportunities for research, experiential learning and community education; and establish leadership in sustainable practices like composting and efficient water use. Together, we can amplify the important work of this botanical treasure and ensure its enjoyment by generations to come.Fullerton Arboretum is a 26-acre botanical garden that serves students, faculty and the broader community as an urban oasis, an outdoor laboratory for research and environmental education, and a steward of worldwide plant conservation and regional agricultural heritage.
