Leaves are large and orbicular with a clefted base. They are dark green and shiny. Fruits are leathery, globose capsules with numerous small gray to orange seeds.

American white waterlily flowers spring through fall. It is tolerant of varied climates, but is typically dormant during cool weather. It occurs naturally in swamps, marshes, slow-moving streams and shallow lakes, ponds and ditches.
