Oddly enough the Calla is not a member of the lily family. It belongs to the Araceae, and its common relatives are philodendron, aglaonema, caldium, anthurium, jack-in-the-pulpit.
This plant is known by several names — arum lily, crowborough, green goddess lily, green spathe, varkblom, and most commonly as Calla lily. The genus was named for Francesco Zantedeschi (1773-1846), an Italian botanist and physician. See more »
