Description

Zantedeschia is a genus of eight species of herbaceous, perennial, flowering plants in the family Araceae, native to southern Africa from South Africa north to Malawi. The genus has been introduced on all continents except Antarctica. Common names include arum lily for Z. aethiopica and calla and calla lily for Z. elliottiana and Z. rehmannii, although members of the genus are neither true lilies of Liliaceae, true Arums, nor true Callas (related genera in Araceae). The colourful flowers and leaves of both species and cultivars are greatly valued and commonly grown as ornamental plants.Zantedeschia shares the general properties of the family Araceae in causing contact irritation. Zantedeschia species are also poisonous due to the presence of calcium oxalate crystals in the form of raphides. All parts of the plant are poisonous, typically producing local irritation or a burning sensation in the mouth and occasionally vomiting and diarrhea. However leaves are sometimes cooked and eaten.Extensive commercial production of Zantedeschia for cut flowers and/or planting material occurs in California, Colombia, New Zealand and Kenya.[21] Plant breeders in California and New Zealand continue to produce an extensive range of new hybrid cultivars. The so-called white calla is derived from Z. aethiopica. All varieties with flowers with shades of yellow, orange, red, purple are mainly derived from Z. albomaculata, Z. pentlandii, Z. elliottiana and Z. rehmanni.
