[2] Zantedeschia aethiopica is a rhizomatous herbaceous perennial plant, evergreen where rainfall and temperatures are adequate, deciduous where there is a dry season.

The inflorescences are large and are produced in spring, summer and autumn, with a pure white spathe up to 25 cm (9.8 in) and a yellow spadix up to 90 mm (3+1⁄2 in) long.

[4] Zantedeschia 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.

The reproduction of Z. aethiopica involves seeds dispersal by birds and vegetative propagation through rhizomes that can spread when soil or garden cuttings are moved.

[citation needed] Zantedeschia aethiopica can be used for treatment of wastewater due to its tolerance of iron and ability to grow in wet areas.
