Or zantedeschia, is a genus of 28 different species all native to the southern parts of Africa with a tropical climate, from South Africa up to Africa aligned with the northern point of Madagascar. The genus calla was originally named by the famous Swedish botanist Carl von Linné but as it became apparent that the genus needed to be split up, the German botanist Karl Koch named the new genus after his fellow botanist Giovanni Zantedeschi from Italy. It became a major hit in Europe and is still very popular, especially as a wedding flower.
