Horticultural Information
Intro: Aquatic perennial from a rhizome, found in lakes, natural depression ponds, old millponds, slow-flowing rivers (blackwater and brownwater), and tidal freshwater marshes.
Stems: Stem consists of a rhizome rooted in mud.
Leaves: Leaves floating or held above water on stout stalks, oval with notched base, to 16 in. long, smooth.
Inforescence:
Flowers: Flowers single on each stalk, held above water, yellow, 1-3 in. wide, cup-shaped; each flower consists of 3 thick, nearly round, yellow to green sepals enclosing many smaller yellow petals, several rings of stamens, and a yellow, columnar pistil with flat top.
Fruits: Fruit an erect, oval capsule constricted at the top (stalk eventually weakens and bends over).
Comments: The most widespread, common Nuphar in e. North America. Other species that may be seen in our area are N. microphylla, N. orbiulata, N. rubrodisca, N. sagittifolia, and N. variegata, distinguished by characteristics such as leaf blade shape and hairiness, number of sepals, stigma shape and color. Consult technical manuals in the Appendix for help in identifying these.
Height: About 6 in. above water
