Zantedeschia aethiopica (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 0.6-1m (2.0-3.3ft) tall, with large clumps of broad, arrow shaped dark green leaves up to 45cm (18in) long. The inflorescences are large and are produced in spring, summer and autumn, with a pure white spathe up to 25cm (9.8in) and a yellow spadix up to 90mm (312in) long. The spadix produces a faint, sweet fragrance.
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.
Z. aethiopica is native to southern Africa in Lesotho, South Africa, Swaziland, Mozambique. It has become naturalised in Malawi, Zambia, Tanzania, Kenya, Madeira and Australia, particularly in Western Australia, where it has been classified as a toxic weed and pest.
A number of cultivars have been selected for use as ornamental plants.
Z. aethiopica and its cultivars 'Crowborough' and 'Green Goddess' have gained the Royal Horticultural Society's Award of Garden Merit.
In order to introduce colours to the large white calla lilies, like the many colours available in the dwarf summer calla lilies, attempts have been made to hybridise Z. aethiopica with Z. elliotiana. These have resulted in albino progeny, which are non-viable.
It has become an important symbol of Irish republicanism and nationalism since 1926 to commemorate the fallen of Easter 1916 and onwards.
It is the national flower of the island nation of Saint Helena, where it grows widely.
The cultivar 'Green Goddess' is listed on the New Zealand National Pest Plant Accord preventing its sale, cultivation and distribution.
