Palomar College is located in North San Diego County, California. Palomar is one of the largest community colleges in the country, in both geographical area and student population. The student population is over 30,000, throughout the district. The main campus is located in San Marcos on a 252 acre site. In 1973, a five acre hillside on the main campus was set aside for an arboretum. Soon thereafter, many trees, palms and bamboos from around the world were planted and labeled, making the arboretum not only an area for the study of botany, but also a place to study, relax and bond with nature. The sciences, photography, kinesiology, anthropology, art, performing arts, and communication classes have used the Arboretum as a place for field trips, class projects and research.

The Palomar Cactus and Succulent Garden is a noteworthy part of the Arboretum. It is located at Comet Circle Drive and Mission Ave on the San Marcos campus of Palomar College. The Palomar Cactus and Succulent Garden has about 40 individual Gardens that provide great examples of Xeriscape and fire resistant plants. The plant collection totals approximately 3,000 different species or varieties form around the globe. The site is a 2 ½ acre plot with .92 of its total size fenced in. The fenced section houses the rare and more valuable species. A host of the other significant accessions can be found scattered throughout the garden, many of which are humming bird and butterfly attractants, as well as many varieties that have ethno botanical uses.

These plant collections are maintained in as natural a state as possible. Few if any pesticides, fertilizers, or herbicides are used in the Garden.
