Water lily

Water lily, (family Nymphaeaceae), family of 58 species in 3 genera of freshwater flowering plants (order Nymphaeales), native to the temperate and tropical parts of the world. 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. Closely related genera, of the family Cobombaceae, are the water shields and the fanworts.

Most species of water lilies have rounded, variously notched, waxy-coated leaves on long stalks that contain many air spaces and float in quiet freshwater habitats. The stalks arise from thick, fleshy, creeping underwater stems that are buried in the mud. The showy, fragrant, solitary flowers are borne at or above the water surface on long stalks that are attached to the underground stems. Each cuplike flower has a spiral arrangement of its numerous petals. [Source]
