Calla lilies are not actual lilies; they are part of the genus Zantedeschia and native to Africa. Calla lilies are a summer bloomer and grow well in mild to hot areas, zone 7 to 10, year round. However, the flowers cannot handle frosts, so if you live in a cold area you will have to dig them up before winter sets in. Calla lilies grow from rhizomes which can be divided in the spring or summer.
