This wildflower was found growing in a spillway drainage from a clump of roots that had grown in the bottom of the spillway. However the spillway was dry and has been for several weeks. There are bodies of water on each side of the spillway. No other such plants or flowers were noticed in this area. I have an image of the bloom and the other one showing the entire plant. Any help with ID would be appreciated. This was located in a wildlife sanctuary in Russellville, Arkansas USA. Thanks!!!
