Thanks Melanie!
I don't have any ruellia, no twinflower, the toadflax has gone dormant now, no snapdragons, haven't found any twinflower lately, no russelia, and the plaintain might have gone dormant by now as it was all over the place a couple months ago but I didn't find any today -- will keep looking. So, I will see if the butterfly bush sustains them.
