Potentilla/cinquefoil

Oh, that explains it! I was searching in the wrong genus! Thanks for your help!

Yes, I'm also not happy about how Houzz changed the forum list around. Trying to find your forum, is like trying to find a needle in a haystack now. I have found that if you google the forum you want, you can get there faster, like if you want the Butterfly Forum, you can google gardenweb butterfly forum. Your plant looks like something in the Aster family, either Rudbeckia, or Helianthus.

commenting on this post: [quote] jekeesl (south-central Arkansas) I tried to find a Helianthus that fits your #2 plant. The two that seem most likely from the keys are H. divaricatus and H. strumosus. If so, your plant is not typical, because those two usually have 10 or more yellow rays. Those lateral veins are too prominent for H. divaricatus, so maybe it is a non-typical H. strumosus. [end quote] I found a photo and very similar comments here regarding the 2 species you mention. The photo does seem to contain some flowers with less than 10 rays and leaves that are very nearly stalkless, as are the leaves in my photo. This supports your hunch that my specimen may be atypical or possibly a hybrid. https://www.michiganflora.net/species.aspx?id=348 To all concerned: All 3 of these flowers were in local county parks and in those parks the vast majority of the park contains "reclaimed" meadow/prairie areas. Those areas have been restored with native plants but may or may not be "naturally occurring" to that area and almost certainly contain a mix of both original and re-introduced native plants. This may explain the problem everyone seems to be having in identifying them, and as noted at michiganflora.net. Especially if seed stock is being shared from one part of the state to another in the restoration projects.
