The Calla lily is also known as Lily of the Nile, Arum lily, and Easter lily.
Although it's a popular subject in many North American paintings -- including several by Diego Rivera and Georgia O'Keeffe and many others -- the plant is not native to this continent. It originated in southern parts of Africa, including Lesotho, South Africa, and Swaziland.
