Scientific Name
Nymphaea spp.
Nymphaeaceae (water lilies)

Water lilies have large, round leaves 8–16 inches across, each with a single V-shaped notch, and each with its own stalk. The leaves may be floating, elevated above the water surface, or submerged, depending on water level fluctuations. The large, showy flowers have many petals that are typically white to pink to violet; the center is often yellow. Blooms July–October. Leaves and flowers are attached to flexible underwater stalks that rise from thick, woody rhizomes (modified underground stems) on the pond or lake bottom.

Similar species: American lotus (Nelumbo lutea) has yellow to cream-colored flowers with a large central disk that resembles a showerhead. The leaves do not have a cleft. Spatterdock (Nuphar advena) has deep yellow, saucer- or globe-shaped flowers and oval or heart-shaped leaves, which are cleft.

Where To Find

Ponds and slow-moving streams, in water up to about 8 feet deep. One species, white (fragrant) water lily (N. odorata), is a native perennial plant that occurs in our state without cultivation; it is also widely cultivated.

Water lilies are among the most beautiful of all water plants and are extensively cultivated. Many water lily hybrids and color forms are available for aquatic gardening, with some hardy and others requiring much maintenance. The Missouri Botanical Garden in St. Louis displays many lovely hybrids.

The undersides of the floating leaves are nurseries for many aquatic insects and snails and thus provide food and shelter for small fish and others. Many insects visit the flowers. Water lilies may grow too rapidly and become a nuisance in some ponds.

About Wildflowers, Grasses and Other Nonwoody Plants in Missouri
A very simple way of thinking about the green world is to divide the vascular plants into two groups: woody and nonwoody (or herbaceous). But this is an artificial division; many plant families include some species that are woody and some that are not. The diversity of nonwoody vascular plants is staggering! Think of all the ferns, grasses, sedges, lilies, peas, sunflowers, nightshades, milkweeds, mustards, mints, and mallows — weeds and wildflowers — and many more!
