Non-native waterlilies (Nymphaea spp.)
Appearance: Perennial aquatic herbaceous plant.
Leaves: Floating or slightly emersed in shallow water. Round with "v-shaped" opening or cleft.
Flowers: Unlike native waterlilies which have white flowers (Nymphaea odorata) or yellow flowers (Nuphar variegatum), most exotic waterlilies have brightly colored flowers including pink, purple, and red. Exotics may also have white or yellow flowers and can be difficult to distinguish from native species. Individual flowers have numerous petals and may bloom all summer.
Seeds: Hybrid species may or may not produce viable seeds.
Roots: Fleshy, buried rhizome that can spread extensively..
