The U. C. Davis Arboretum was founded in 1936 to support teaching and research at the University of California. The Arboretum occupies 100 acres along the banks of the old north channel of Putah Creek in the heart the Central Valley and is the main source of horticultural information for inland California.
The Central Valley has a climate of extremes. Temperatures in Davis range from 14°F to 118°F, and average rainfall is only 19 inches per year. The 17 gardens and collections include 22,000 trees and plants adapted to this climate. Plants are arranged in a series of gardens that represent different geographic areas, plant groups, or horticultural themes.
An online Living Plant Collection Database allows searches by scientific or common name, and displays their physical location within the Arboretum.
Some of the more unique displays include a Valley-wise garden, featuring plants especially well suited to the Central Valley; a White Flower Garden based on medieval moon-viewing gardens of India and Japan; the Shields Oak Grove collection of more than 80 kinds of native oak trees; and an Early California Garden representing the rancho period of 1840-60.
