Dudleya brittonii

Dudleya brittonii, with the common names Britton's dudleya, Britton's liveforever and giant chalk dudleya, is a large succulent plant in the family Crassulaceae, the same genus as jade plants. It is native (possibly endemic) to the coast of northern Baja California, Mexico. Uniquely, Britton’s Dudleya has a green form, or variant of the white form. Both forms of the plant have yellow leaves on a clustered rosette atop a large reddish-purple peduncle. The white form of the plant has a chalky epicuticular wax that reflects light and reacts with water. The green form of the plant is more common and found throughout a wider range. It is among the largest of the Dudleya genus....read more on Wikipedia.
