I took this photo in 2009, and just discovered it again. I never did identify it the first time around. It was in a shaded ditch along a forest road. Any idea of species?
It looks like Stokes Aster (Stokesia laevis). I have a couple named varieties that look very similar.
Here is a link that might be useful: Stokesia laevis - Mobot Website
That's what I was looking for. Thanks, guys, for the help.
