Other info. - This is a showy plant which sometimes forms large colonies. The big white flowers
and palmate leaves are unmistakable.When fresh, the
petal-like sepals are brilliantly white, often faking camera light meters into underxposure. The plant is found in scattered locations in
Missouri, predominantly in counties bordering the Missouri River. It U.S. range comprises two distinct regions - one across the upper Midwest
and Northeast (with Missouri near the southern end of this region), the other along the Rocky Mountains southward into New Mexico.
An odd but consistent habitat preference for this species is levee banks.
Because it favors locations near water, you may encounter other interesting species when hunting the plant. One
such species is Nerodia sipedon sipedon.
