--><p>Nymphaea is an important genus of ornamental plants, with numerous cultivars or wild forms grown in water gardens. Some have become naturalized in some places, particularly in Florida, and two such taxa are included in this treatment. A third, N. ×daubenyana W. T. Baxter ex Daubeny (N. micrantha Guillemin & Perrottet × N. caerulea Savigny), with blue flowers and entire leaves and with a proliferous mound of fibrous tissue above insertion of petiole, may also be encountered in Florida.</p><!--
--><p>Prior to conservation in its current sense, the name Nymphaea was frequently used for the genus now known as Nuphar.</p>
