This is a cool little flower. It has been suggested that the name comes from the look of the plant and the fact that it grows in what used to be Miami Indian territory. With the fringed petals, a large grouping of this plant might look like mist coming off the ground.
It is very pretty up close. The petals have more of a fringe than any other plant I’m aware of. We found this plant growing near the Eel River in Indiana during a canoe trip. It was seen in several places, not along the river but higher up on the banks in wooded areas. I believe they need rich wooded areas without a lot of shade.
