Tucson Botanical Gardens, Botanical garden in central Tucson, United States.

Tucson Botanical Gardens is a five-acre park in central Tucson featuring sixteen separate garden sections. The grounds hold Sonoran Desert plants, herbs, tropical species, and specialized plant collections throughout the property.

The garden was founded in 1964 by horticulturist and collector Harrison G. Yocum, who opened his private cactus and palm collection at his own home. In the early 1970s it moved to the Porter estate, whose adobe buildings date to the 1920s; Bernice Porter had donated the property to the City of Tucson in 1968, and a 1974 City Council resolution designated it for a botanical garden.

The gardens display medicinal herbs and plants important to indigenous communities of the Southwest, letting visitors explore these living collections firsthand. You can see how these species fit into the region's daily life.

The entrance is free. The site lies at 2150 North Alvernon Way in Tucson, Pima County, Arizona. Tropical butterflies from around the world are shown in the Cox Butterfly and Orchid Pavilion from October to May, so plan that part of a visit within those months.

The Cactus and Succulent Garden holds fossils, minerals and stones that founder Harrison G. Yocum collected himself. Yocum opened his private cactus and palm collection to the public at his own home in 1964, before the gardens moved to the Porter estate.
