American lotus leaves are round and centered on the petiole, and can measure up to 2 feet in diameter. Only one leaf is connected to a petiole.

Flowers

Fruit
Fruits are acorn-like and embedded in a fleshy, cone-shaped receptacle that later becomes dry and woody. Plants are generally in flower from July to August.

Identifying Characteristics
American lotus is similar in appearance to water lilies but does not have a "cut" or "notch" in the leaf like the water lilies do.
