Dudleya cymosa is a succulent plant known by the common name Canyon live-forever. The plant is found in rocky areas in the low elevations of California and southern Oregon mountains.
It is a distinctive plant sending up erect red-orange stems from a gray-green basal rosette. The small yellowish-red thimble-shaped flowers top the stems in a cyme inflorescence. Some subspecies are considered threatened locally.
