Fullerton Arboretum
The Fullerton Arboretum is a 10 ha (26 acre) 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, USA. The Arboretum officially was created in 1976, and officially opened in 1979. 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 restored house now serves as a museum of family life and medical practice of the 1890s. 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 11,000 ft 2 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 Orange County Agricultural and Nikkei Heritage Museum is located on the grounds of the Fullerton Arboretum, and highlights the region's agricultural history, as well as the contributions of the local Japanese American community and other pioneering farmers. The museum is a collaboration between Fullerton Arboretum and California State University Fullerton. Heritage House is a historic house museum decorated as a doctor's home and office of the 1890s. The Eastlake-style cottage was built by one of Fullerton’s pioneer doctors, Dr. George Crook Clark, in 1894. The home was moved to the arboretum campus in 1972 to save it from demolition. It was originally located at the corner of Amerige and Harvard (Lemon) in the center of Fullerton. Docents lead tours of the house on weekend afternoons.
