Giant Lily, or Victoria Amazonica (after my dear Queen) is a genus of water lilies, in the plant family Nymphaeaceae (how do you pronounce so many vowels together?), with very large leaves that float atop the water's surface. The leaf can go up to 3 meters (9.8 feet) in diameter, on a stalk 7-8 meters (22.9 - 26.3 feet) in length. You could even stand on one of those!
While talking of lilies, we mustn't forget Claude Monet, and his famous lilies! Even he found something magical about them that he had to make them immortal. I really find something so erotic about lilies, it makes me think of private ponds and harem girls :P .. though Monet's work certainly doesn't project such a perception :D
