Water lilies grow in nearly every geographical region in the world, depending on the type of water lily. Hardy water lilies survive all climates, while tropical water lilies can only handle tropical climates, and must be treated like annuals.
Water lilies, as the name suggests, grow in water. Ideal locations include a pond or a tub that can withstand the water. There are pots beneath the water's surface that hold soil and the water lily seeds. Above that, water is filled nearly to the top of the tub. In ponds, they are planted in the soil beneath the pond. Once the stems rise from the soil, they peek out of the water's surface and display star-shaped blossoms that float on the water.
