This Dudleya is endemic to southern California, where it is rare and seriously threatened as its habitat is altered by humans.

The flowers, which appear in late spring, have pointed yellow petals and long stamens.

There are 7 to 18 strongly ascending bracts, with a similar linear shape to the rosette leaves.

The petals are connate for 1–2 mm (0.039–0.079 in), and spread from the near middle, colored a bright yellow to a fading pale-yellow, and often lined-red at the keel.

[3][4] Dudleya multicaulis is endemic to the Los Angeles coastal plain and the adjacent hills, parts of the Transverse and Peninsular ranges, and south towards northern San Diego County.

D. multicaulis is primarily found on heavy soils, usually clay, rocky hillsides, and sandstone outcrops.
