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.

Selected subspecies:

• D. c. subsp. costafolia - Pierpoint Springs dudleya
• D. c. subsp. crebrifolia - San Gabriel River dudleya
• D. c. subsp. marcescens - marcescent dudleya
• D. c. subsp. ovatifolia - Santa Monica Mountains dudleya

Dudleya cymosa is the larval host plant for the Sonoran Blue butterfly, Philotes sonorensis (Lycaenidae)
