Even without a calendar these plants would tell you it’s August here in Ohio.
The Ragweed plants, both Common as seen here and Giant, grow in abundance in fields and along roadsides. The flowerheads have begun to release pollen. They peak during the last two weeks of this month and the first two of September but will continue to some degree untill October or a killing frost. If you’ve noticed that your nose is running and your eyes seem tired or itchy these guys are probably why.
The Morning Gloys have intertwined with the corn climbing 10 feet or so. Their flowers can be blue, purple, pink, or white.
