Pig's ear (Cotyledon orbiculata), also known as round-leafed navel-wort, is a South African succulent plant belonging to the genus Cotyledon in the family Crassulaceae, also known as the stonecrop family or the orpine family. It has gray-green leaves, which naturally develop a white, powdery substance (known as farina) on their surfaces this farina helps reflect sunlight and conserve water. The shape of the leaves was thought to have a resemblance to a pig's ear, thus the common name. The bell-shaped flowers, which appear in winter, are usually a blood orange-red or a paler salmon-orange yellow varieties also exist.
