Dudleya cymosa (Lem.) Britt. & Rose is a perennial low-growing succulent plant species that is endemic to California. Having a number of subspecies, this fleshy plant is most frequently known as Canyon liveforever. This smooth leaved succulent taxon is quite often found among outcrops on rocky slopes in lower elevation mountains. Some of the subspecies are of highly restricted distribution, and most subspecies are associated with rather specific rock outcrop types as well as well defined mountain ranges. Elevations of occurrence vary from 50 to 2700 meters, with significant differentiation among some of the subspecies.
