Dudleya brittonii

Dudleya brittonii (DUD-lee-yuh brit-TON-ee-eye), with common names Britton's dudleya and Giant Chalk Dudleya, is a succulent plant in the Crassulaceae family. It is native to Baja California, Mexico.


The leaves of Dudleya brittonii grow in a basal rosette and are covered with a dusty, chalky, mealy white epicuticular “wax”. The wax in its mealy state on the leaves is attracted to water and coats drops on the leaves and prevents their evaporation. The wax has the highest measured ultraviolet reflectivity of any plant.[1]

Dudleya brittonii is similar in appearance to Dudleya pulverulenta, native to California.


Dudleya brittonii is cultivated as an ornamental plant for use in well drained rock gardens and as a potted succulent. [2]
