Moorten Botanical Garden and Cactarium

The Moorten Botanical Garden and Cactarium is a 1 acre family-owned botanical garden in Palm Springs, California, specializing in cacti and other desert plants. The gardens lie within Riverside County's Coachella Valley, part of the Colorado Desert ecosystem.

History
The Moorten Gardens were established as a nursery in 1939 by Patricia and Chester "Cactus Slim" Moorten, and developed into the present day garden in 1955. Chester, one of the original Keystone Cops, starred in Two Flaming Youths (1927) and The Sideshow (1928). The Moorten residence was named the Cactus Castle, and was originally built in Mediterranean style by photographer Stephen H. Willard (1894–1966). The Moortens collected many of their own specimen plants from Baja California, mainland Mexico, and as far south as Guatemala. To recognize their contributions to the community, the Moortens were awarded "Golden Palm Stars" on the Palm Springs Walk of Stars.
