Zantedeschia aethiopica, commonly known as calla lily and arum lily, is a species in the family Araceae, native to southern Africa in Lesotho, South Africa, and Swaziland. Zantedeschia aethiopica is a rhizomatous herbaceous perennial plant, evergreen where rainfall and temperatures are adequate, deciduous where there is a dry season. Its preferred habitat is in streams and ponds or on the banks. It grows to 0.6–1 m tall, with large clumps of broad, arrow shaped dark green leaves up to 45 cm long. The inflorescences are large and are produced in spring, summer and autumn, with a pure white spathe up to 25 cm and a yellow spadix up to 90 mm long. The spadix produces a faint, sweet fragrance.(wikipedia)
