They occur worldwide, often in shallow, still water in lakes and ponds, where they spread rapidly, the leaves form floating carpet. Leaves are 1-6″ diameter oval or rounded with heart shaped bases, or kidney shape and are slightly glossy and olive green occasionally purple mottled and wavy edged.

Grow in a wildlife pool with waterlilies or Nuphar species.
Outdoors, grow hardy species, and tender species in frost free areas, in water no deeper the 4-18″ in full sun. In a small pool contain within an aquatic container, in a large pool or lake, growth is limited to shallow margins.
