Zantedeschia aethiopica

Zantedeschia aethiopica (common names calla lily, arum lily; a.k.a. varkoor, an Afrikaans name meaning 'pig's ear') is a species in the family Araceae, native to southern Africa in Lesotho, South Africa, and Swaziland.

It 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 (2–3 ft) tall, with large clumps of broad, arrow shaped dark green leaves up to 45 cm (18 in) long. The Inflorescences are large, produced in spring, summer and autumn, with a pure white spathe up to 25 cm (10 in) and a yellow spadix up to 90 mm (3½ in) long.

Z. aethiopica contains calcium oxalate, and ingestion of the raw plant may cause a severe burning sensation and swelling of lips, tongue, and throat; stomach pain and diarrhea may occur.
