Thanks for your detailed post and photos. I've been debating about harvesting seeds from a different ironweed species, and your post definitely encouraged me to wait a while longer.

Did you get the expected results from your germination experiment?

10/9/23 Here is my report on the seed germination. I counted out 24 seeds of each group and kept them separate. I gave them the same damp-cold stratification and the same conditions. To my immense surprise, the ones I picked early almost all germinated. Only 4 of the ones that I picked later germinated. So my theory seems not to have been correct. This fall I picked them (a few days ago) when they were formed but not flying away.
