Wetland indicator: Obligate
This plant seems to have about a dozen names and various subspecies and varieties. The way I learned some members of this genus, and it makes a simplistic sort of sense, is that Spatterdock tends to have mostly emergent, upright leaves and few floating leaves, while Bullhead Lily has leaves that mostly float horizontally on the surface of the water (unless the water level is below soil level). My experience growing various wild and cultivated plants is that individual plants will favor one of these growth habits regardless of the growing conditions.
Browsing Crow & Hellquist it would appear that N. advena would fit the description for Spatterdock, with the additional traits of having red-tinged fruits and inner surfaces of sepals. Bullhead Lily is attributed to N. variegata Engelm. ex Durand.
