Zantedeschia aethiopica is a rhizomatous herbaceous perennial plant, evergreen where rainfall and temperatures are adequate, deciduous where there is a dry or cold season. Its preferred habitat is in streams and ponds or on the banks of rivers. 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 (3 1⁄2 in) long. The spadix produces a faint, sweet fragrance.
Zantedeschia aethiopica is best grown near or in water. If that is not the case, it can be planted in semi-shade.
It makes an excellent cut flower. Some interesting varieties are also available such as “Green goddess” and “Marshmallow”.
This is the only Zantedeschia that is evergreen – all the others are deciduous.
