Common names: Calla lily, Arum lily, African lily, White Calla Lily, Egyptian lily, Lily of the Nile, Richardia, Trumpet lily, White arum lily, Altar lily. This species is native to southern Africa. They are herbaceous tuberous plants that reach 1 meter (3.28 feet) in height. The large, neat or heart-shaped basal leaves are deep green in color. The flowers are yellow and surrounded by a large white bract; there are yellow or pink cultivars. They bloom in spring and summer. Calla lily is used in shallow ponds, in clear understory, and in pots for balconies, terraces, patios, and greenhouses. It's also used as cut flowers. Zantedeschia aethiopica prefers a semi-shade exposure; avoid direct sun in the hottest hours of the day. It does not resist frost. The soil must be acidic and contain abundant organic matter. Water abundantly so that the substrate never dries out; they are semi-aquatic plants. White Calla Lily does not resist drought. Fertilize with mineral fertilizer every 20 days during the flowering period. African lily does not need pruning. Dig up the tubers during the dormant period (winter). Zantedeschia aethiopica is a fairly easy growing plant that does not usually present serious pest and disease problems if it does not suffer from drought. White arum lily is propagated by division of the tubers in spring. Plant them 15 cm (5.9") deep in large pots. |
