We were there as a field trip that was part of the annual Midwest Native Plant Conference (our 12th one) near Dayton. After having to skip last year due to Covid, it was great to once again have the conference. It was at a slightly reduced level due to facility restrictions, but nonetheless there were 150 attendees and all went great. Kudos to the organizers for a tremendous job. If you haven't been, try to make it next year. It does fill up quickly, take note.
An important part of the conference is a legion of vendors, all selling native flora. We are always amazed at the incredible diversity of plants that are available, including hard to find species. I took home some botanical goodies, including a nice specimen of Wafer-ash, Ptelea trifoliata. This shrub/treelet is one of only two host plants in our region for the Giant Swallowtail. Who knows, with some luck maybe my plant will lure a female in to lay eggs on it.
