Very Unusual Flower on Black Magic

Two of our Black Magic Elephant Ears have blessed us with a very dramatic flower. According to a website my wife found: "The inflorescence, which is rarely produced in cultivated plants, is a pale green spathe and spadix, typical of the arum family." The site has interesting information on how this plant is used for food. http://www.floridata.com/ref/c/colo_esc.cfm Of course I like the idea that this flower is unusual in cultivated plants because it reinforces how plant friendly our pondscape is.
