It is the largest species among the family Crassulaceae. The stem is woody with a diameter of 5–7 cm and height of more than 3 m. The leaves are triangular and cut into the pinnate, and the leaf edges are undulate. There are two types of trichomes (glandular hair) on the surface of the leaves: non-glandular protrusions that branch into three parts and densify and head-like glandular protrusions. It is a CAM plant and has strong xerotolerance. Propagation is performed by seeding, stem cutting, or leaf cutting (adventitious bud).
