Those seed heads look a lot like Bidens. Any chance it could be Biden’s bipinnata or something?

Looks like that to me as well.

Bidens bipinnata looks like a match in flower and leaf. They are supposed to grow between 2 and 5 feet tall. The plants I saw were about 6" tall, but it's the only Bidens species that fits. I went through them all. Everything in Asteracea will push out blooms from tiny plants if conditions aren't ideal, so I think that's what's going on here, it just seems unusual to have a bunch of them all in that same, stunted condition. The leaves made me think Bidens. The size of the plants threw me. Thanks mac and Carol!

I collected seeds so I can test the theory, tho I'm not crazy about the miserly flowers. There are just a few Bidens species native to here that I like. Aristosa, polylepis and cernua. Trichosperma is nice too, but needs wet feet.

At the same place.......
