There are two ways of propagating this plant. If the flower stems are allowed to rise above the water surface, it will produce small yellow flowers that will seed if pollinated by a small brush. The seeds can then be potted in moist soil to produce new plants. It is also a rhizome plant so this can be divided into smaller pieces to produce several plants from one rhizome.
This plant produces waxy, arrow shaped leaves that look very similar to the Nymphea species. When the plant flowers, it will produce small, yellow blooms unlike the larger white flowers that the lilies produce. The rhizome is used as an ingredient in cooking in some countries and some cultures also use this plant for medicinal purposes.
