*Nymphaea* is a genus of hardy and tender aquatic plants in the family *Nymphaeaceae*. Plants of the genus are known commonly as water lilies. Water lilies have several edible parts. The young leaves and unopened flower buds can be boiled and served as a vegetable. The seeds, high in starch, protein, and oil, may be popped, parched, or ground into flour. Potato-like tubers can be collected from the species Nymphaea tuberosa. [https://en.wikipedia.org/wiki/Nymphaea]
