Calla Lily (Zantedeschia) is a genus of twenty-eight species of flowering plants in the family Araceae, native to southern Africa from South Africa north to Malawi. The name of the genus was given as a tribute to Italian botanist Giovanni Zantedeschi (1773-1846). Common names include arum lily, calla, and calla lily.

The flowers are produced in a spadix, with a large, brightly coloured bract surrounding the inflorescence.

All zantedeschias produce large, showy flowers spathes and are often grown both as ornamental plants and for cut flowers.
