This landmark botanical garden has been delighting Palm Springs visitors for more than 60 years. Proudly proclaiming itself the "World's First Cactarium," the garden includes 3,000 fine examples of desert cacti and other desert plants, in a quirky Wild West setting sometimes used as a film backdrop. Turtledoves, hummingbirds, lizards and other small wild creatures also make impromptu appearances among the rocks and plants. Many unusual botanical specimens are for sale, along with other souvenirs.

The Moorten Botanical Garden and Cactarium 1 acre is a family-owned botanical garden specializing in cacti and other desert plants, located at 1701 South Palm Canyon Drive, Palm Springs, California, USA. It is open to the public for a fee.

The Gardens were established in 1939 by Patricia and Chester "Cactus Slim" Moorten, one of the original Keystone Cops. The Moortens collected many of their own plants from Baja California, Mexico, and as far south as Guatemala.

Today the garden includes 3,000 examples of desert cacti and other desert plants, grouped by geographic regions: Arizona, Baja California, California, Colorado, the Mojave desert, the Sonora desert, South Africa, arid South America, and Texas. Outdoor collections include agaves, bombax, crested Cereus, cardon and boojum trees, arborescent "candelabra" Euphorbia, a two-story Pachypodium, thorned Caesalpinia and Bursera, and some dozen aloes of southern Africa and Madagascar. In the "Cactarium" greenhouse are cacti and succulents, with caudiciform species exhibiting thickened root crowns (caudex), many species of Asclepiads, Aztecia, Gymnocalyciums, Alstromeria, Euphorbia, and Ferocactus, plus two fine examples of Welwitzia mirabilis from Namibian deserts.
