Usually with white petals, one may encounter individuals showing pink petals even sometime almost red.
This coloration may occur on a rhizome which bears white flowers and even varied from year to year for the same individual.
The difference in coloring is probably related to changes in water level of the habitat.
The flowers open each morning and closes in late afternoon.
The leaves, almost perfectly round, have a waxy substance on the top making them waterproof.
Once fecundated, the fruit is pulled under water where it will develop.
Includes two subspecies (See the Identification tab).
