Graptopetalum macdougallii is a caulescent, succulent plant with its leaves arranged in rosettes. It may form stout clumps up to1 m in spread by means of short stolons and axillary basal shoots or stems. It has a shimmering blue-white colouring that gives it a delicate beauty. A protective waxy powder that covers the succulent leaves provides this colouration. The flowers are c. 2.5 cm across, each with 5 petals marked with dense red lines. This species is most attractive.
