Roadside wildflowers

I'm traveling through Iowa today and really enjoying seeing native prairie plants along the side of the highway. We hve seen purple coneflower, black-eyed Susan, hoary vervain, butterfly weed, yellow coneflower, yellow coneflower and wild beramot in bloom as we wiz past at 70 mph. Thought they are mixed in with quite a few weeds (they could use a good prescribed burn!), none the less it is encouraging to see Iowa taking this critical step to te long-term preaevatipn of our native wildlife.
