Did you know that that water lilies are not really lilies? Other then the fact that they are both plants there is no relation at all. Most water lilies belong to the family Nymphaeaceae in the order Nymphaeales where lilies belong to the Liliaceae family in the order Lilales. Water lilies are not the only non-lily lilies, day lilies and spider lilies are also not really lilies. I photographed this tropical water lily at the water gardens at the Como Zoo and Conservatory this summer.
