Native to California, Arizona, coastal Oregon, Baja California. About 40 species are known, some common on California’s coastal cliffs or inland hills.
Best known species in cultivation is Baja California native, with 1 1/2 -ft.-wide leaf rosettes on stems that gradually lengthen into 1- to 2-ft. trunks; these lean or become prostrate as the plant ages. Fleshy leaves are covered with a heavy coat of chalky powder that can be rubbed off. When plants flourish, they produce reddish stalks with little yellow flowers in spring. Striking plant when well grown; needs bright light and shelter from rain, hail, and frost. Best under glass or plastic roof to keep powder from being washed off.
Gray, woolly, inch-long leaves are marked with white. Often grown as an annual.
