Large, widespread, glaucous white Dudleya from California, Baja California, and Arizona with red tubular flowers. Leaves are usually very glaucous and rosettes are usually (but not always) solitary. A pioneer species. Stems of the type subspecies are the widest of any Dudleya species, and stems may grow decumbent to about 18" long. Rosettes range from about 6" to 30" wide in extreme cases, and are much larger in winter. Best color and form in strong light. May be short lived in containers but can survive decades in the ground.

This species looks very similar to the white form of D. brittonii (which overlaps a bit in range) but the two can be definitvely resolved based on the flowers (pulverulenta's are long and red, not medium and yellow-green) and usually distinguishable based on the thickness of the leaves (brittonii much thicker). D. pulverulenta also closely resembles D. anthonyi, a coastal species from near San Quintín, Baja California. D. anthonyi flowers are narrower, and the sepals are much shorter.

Dudleya pulverulenta is mostly found close to the Pacific coast, but several populations also exist inland, all the way to Arizona. The inland subsp. arizonica tends to be less glaucous and smaller than the type subspecies.

Released by the ISI in 1962 and 1995.
