Kalanchoe marmorata (penwiper) is a species of flowering plant in the family Crassulaceae, native to Central and West Africa, from Zaire to Ethiopia, Sudan and Somalia. It is an erect or decumbent succulent perennial growing to 40 cm (16 in) tall and wide, with glaucous leaves spotted with purple, and starry white, four-petalled flowers, sometimes tinged with pink, in spring. As the minimum temperature for cultivation is 12 °C (54 °F), in temperate regions it is grown under glass as a houseplant. The Latin specific epithet marmorata refers to the marbled surface of the leaves.
