Photograph of a boy riding on a Victoria Cruziana water lily pad in the middle of the pond, Huntington Gardens, San Marino, ca.1920. A variety of water lilies and plants populate the pond. Rocks surround the shores of the pond.; "The largest water lilies are those of the tropical South American genus Victoria, comprising two species of giant water lilies. The leaf margins of both the Amazon, or royal, water lily (V. amazonica; formerly V. regia) and the Santa Cruz water lily (V. cruziana) have upturned edges, giving each thickly veined leaf the appearance of a large, shallow pan 60 to 180 centimetres (about 2 to 6 feet) across and accounting for its common name, water platter. The fragrant flowers of Victoria have 50 or more petals and are 18 to 46 centimetres (about 7 to 18 inches) wide. They open white toward evening and shade to pink or reddish two days later before they wither, to be replaced by a large berrylike fruit. Water lilies provide food for fish and wildlife but sometimes cause drainage problems because of their rapid growth. Many varieties have been developed for ornamental use in garden pools and conservatories." -- unknown author.
