Do you recognize this plant?
I have seen it growing alongside the
Blue Ridge Parkway between Roanoke and Floyd, Virginia.
It is also growing on the bank behind my home in Roanoke along the edge of the woods.
I'm thinking that it might be in the same family as Madder (Rubia tinctorum) which immediately makes me wonder if this would be a good dye plant!
UPDATE: Well. I still don't know if it would be a good dye plant or not, but I have been told that this is Sericea lespedeza.
It is considered to be a noxious weed in many states.
