Water lilies encompass approximately 70 distinct species, categorized as either tropical or hardy varieties. These plants thrive in water depths ranging from 3 inches to 3 feet, with their spread varying between 2 to 20 feet. Larger species require more expansive water gardens or ponds, while smaller varieties flourish in containers. They thrive best in still water, avoiding areas with fountains or strong currents. Most water lilies prefer full sunlight, although some can adapt to partial shade. Their striking flowers are often fragrant, complemented by their attractive lily pads. Notably, viviparous water lilies produce plantlets that remain attached to the parent plant.

One specific variety, 'Helvola,' commonly known as the Yellow Pygmy, is a hardy dwarf water lily. It features vibrant yellow blooms that are prolific and is particularly well-suited for small water gardens or containers. This variety can also tolerate partial shade.
