Nymphaea ampla - Enjoy the dreamy and relaxing effects of these beautiful white lily flowers. Lilies (in fact a kind of lotus) enjoyed special significance to the peoples of Ancient Egypy. The flowers of the Egyptian blue water-lily (N. caerulea) open in the morning and then sink beneath the water at dusk, while those of the Egyptian white water-lily (N. lotus) open at night and close in the morning. Egyptians found this symbolic of the separation of deities and of death and the afterlife. Remains of both flowers have been found in the burial tomb of Ramesses II. According to some sources white lily is also a potent aphrodisiac.
