Black snake root is one of those plants that comes up at these plant forums again and again, and there's no decent pictures to be found for it online...

I was recently attempting to shoot pictures, and I couldn't do any better...
I'm going to have to stop digging this plant out... until I get some decent pics...
Some shots of the rosette, and the flower, and the entire plant with seeds... All from the same specimen... would be a start...
But who remembers to shoot their weeds?
