Cotyledon orbiculata, commonly known as pig's ear or round-leafed navel-wort, is a South African succulent plant belonging to the genus Cotyledon. It has naturalized and is invasive in several subtropical countries like Australia and New Zealand.
The Cotyledon orbiculata is a robust evergreen succulent shrublet with brittle stems 50-120 cm tall, 80-150 cm wide often quite densely branched. It one of the oldest grown succulents being introduced as long since as 1690 by Mr Bentick that still retains a place in most collections for the magnificent glaucous colour of its foliage and its large flowers of long duration. It is one of the most complex specie, not only because of its seemingly endless range of variation, but also because many of its numerous forms have been formally described. The several varieties and forms enumerated are differing chiefly in the form of their foliage. Leaves, stems and flowers have a waxy bloom. It can be invasive in Australia and New Zealand.
