Dudleya cymosa is a succulent plant known by the common name canyon live-forever. 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. The plant is found in rocky areas in the low elevation mountains of California and southern Oregon. Some subspecies are considered threatened locally.
