Roadside: Yellow wild flower

Photos taken along a country road on July 14. They weren't far from St. John's Wort but these are different. Also not wingstem. Any ideas?

I'm not sure. These look smaller to me and I'm not seeing hairs on the stems. I wish I had photographed the lower leaves because those, apparently, are distinctive in Jerusalem Artichokes. Even so, you might be right.

Almost for sure, it is a **** yellow composite (DYC):

Re: Roadside: Yellow wild flower

Here is something that might be a little more helpful (emphasis on "might"): A Bidens?

This one is reported in Ohio but not in Michigan . . ?

ROFL! I don't know if it's a Bidens or not but I have learned about a new plant, the DYC. I've never heard that expression before, but the article says even Ladybird sed it. That made my day.

Re: Roadside: Yellow wild flower

This plant is very common in southern Wisconsin and northern Illinois and Indiana. I see these a lot in the fields around here. My guess is some kind of sunflower.

I was interested to see that the article says that "Jerusalem Artichokes belong to the sunflower family and are almost impossible to distinguish from the common sunflower without looking at the roots." So maybe that's it.

Or, maybe it's the Maximillian sunflower referred to in that article: "The Maximilian sunflower is a common perennial sunflower that is often mistaken for Jerusalem artichoke."

Apparently, you have to dig for the tubers to find out which it is!

Cheers.

Re: Roadside: Yellow wild flower

All of your suggestions are very good and, as always, give me leads to plants I haven't shown, yet. I may have to dig one up next year to look at its roots. These particular flowers are growing on state property but most prisons allow some computer time, don't they? I'll let you know.
