I was at the lake this weekend in OK, and came across a hardy hibiscus. I didn't have my camera to take a picture. It is hardy, but the leaves were long, thin, and tri-lobed. Almost like a bird's foot. I haven't been able to find anything quite like it. It was a creamy white (not yellow) with a red eye and red brushed lightly on the backs of the base petals. I collected several seed pods off of it, but would like to know what it is that I have. This was growing down by the water near the honeyball bushes.

Does anyone have any ideas of where to start looking? I've Googled and Googled under different headings.

Thanks!
