The photographer, Tom Harnish, writes that Zantedeschia is often misnamed Calla: “Zantedeschia is a different genus than Calla – not a small distinction if you consider that dogs and cats are two different genera (Canidae and Felidae). Imagine going into a pet store and seeing signs over the puppies that indicate they’re cats? Oddly, most garden shops label these flowers calla (even cala) lilies, and that’s what most people call them. Zantedeschia, shown here, are from tropical Africa, and should not be confused with the smaller white calla that grows in bogs of northern Europe, Asia, and North America.”
