| Description: | Rooted aquatic plants with 5-16" floating, round or elliptic leaves with a cleft on one side; the white or colored 2-7" flowers are often fragrant and are floating or borne above water. |

| WARNING: | Water lilies spread aggressively once introduced into freshwater bodies. Spread is by seed, rhizome, or plantlets formed on adult plants. |
