I also caught a picture of a tiger swallowtail on the coneflowers. The coneflowers have had a banner year.
Here's an update on the pot of volunteers. If I get a chance, I'll separate the plants.
(My camera doesn't capture purple colors very well. In researching on the web, I've found that problem is not uncommon with my kind of camera. It has to do with the white setting, but I don't know if that is something that requires a technician to change. So the petunia really doesn't look in real life like it looks in the picture, but it does still clash in real life with the coleuses. Until I have a chance to separate them, though, I will just refer to them as a "riot of color.")
