The Fullerton Arboretum is a botanical garden with a collection of plants from around the world, located on the northeast corner of the California State University, Fullerton campus in Fullerton, California, in the United States. It is the largest botanical garden in Orange County, with a collection of over 4,000 plants. The Arboretum saves species that are extinct or near extinction and serves as a learning place for agricultural history. The Arboretum officially was created in 1976, and officially opened in 1979. The arboretum, which was originally a diseased orange grove, was transformed into organic gardening plots. A centerpiece of the Arboretum is the Heritage House, which was built in 1894 as the home and office of Fullerton's pioneer physician, Dr. George C. Clark. In 1972 the house was moved to what is now the middle of the Arboretum. The Arboretum's garden paths wander through four major collections: Cultivated, Woodlands, Mediterranean and Desert Collections. Highlights include Southern California native vegetation, Rare Fruit Grove, an organic vegetable garden, historic Citrus and Avocados, Channel Islands Garden, an extensive Cycad Collection, Conifer Collection, Palm Grove, Community Gardens, and a Children's Garden. The Arboretum gives people the opportunity to teach and learn about the environment. They work with students and faculty from a variety of different campus departments and gather information. The research that is done is shared throughout Orange County. History The idea of creating an arboretum on the northern part of Orange State College's campus, later known as California State University Fullerton, came from Drs. David Walkington and Eugene Jones. The land had originally been an orange grove and suffered a disease called "quick decline", which led to the death of the trees. Teri Jones, along with other faculty wives, worked together to find support for developing the land into an arboretum. The Arboretum Committee was formed and they later won a Disneyland Community Service Award for its environmental efforts. The Associated Students of Cal State College started funding for the project in 1971. Students and faculty worked together to use the land for organic gardening plots to show the environmental values of organic gardening. The trees were cut down and roots were removed. In 1972, the idea of setting the land aside for a botanical garden came about. The Arboretum Society was formed and they started fundraisers on campus to build a botanical garden. They also asked the City of Fullerton
