Spatterdock, Cow lily
(Nuphar lutea subspecies advena)
Spatterdock is a large plant whose leaves are often floating, however
submersed and emersed leaves are common.
Spatterdock has large heart-shaped leaves, usually with wavy margins.
Spatterdock floating leaves are attached to long, stout stems which arise
from large, spongy rhizomes. Spatterdock submersed leaves are very thin,
attached at the bottom rhizomes. Spatterdock flowers are yellow and "half-opened"
at or above the water surface. Flowers are attached to thick round stems
that are often six feet long.
