A description of Nuphar advena is provided in The Flora of North America.
Distributed north to Michigan, south to Florida, and far west as Texas.
N. advena is an aquatic perennial that requires protection from strong current. In the Coastal Plain in Florida, it has been observed growing in ponds of pine-oak forests, ditch ponds, and still river water. Associated species include Brasenia and Nymphaea. 
Flowers May through November and fruits in September. 
Typical N. advena fruits are green with green stigmatic disks, anthers, sepals and fruit walls; however, Padgett (1996) reports of a population in southeastern Virginia having red fruit walls. Characteristically this species lacks red pigmentation.
In areas of sympatry, it can intergrade with N. orbiculata, N. variegata, N. ulvacea, and N. sagittifolia.
The following Hymenoptera families and species were observed visiting flowers of Nuphar advena at Archbold Biological Station: 
Apidae: Apis mellifera
Colletidae: Hylaeus schwarzi
Halictidae: Lasioglossum nelumbonis
Use by animals
It is a food source to some turtles: Chelydra serpentine (snapping turtle), Chrysemys picta (painted turtle), and Stenotherus odoratus (musk turtle). Muskrats and beavers have also been observed to eat the plant, especially the rhizomes and lower petioles.
