We picked up some blue mistflower (Conoclinium coelestinum) along with some other plants that were being given to us. It’s spread around the yard and now we have both the normal pale blue, as seen here (it’s more blue than this photo makes it look) and a white sport (or perhaps the blue is the sport). It blooms late in the summer, just starting now, and will be around into the fall. I don’t know that I’d run out an buy any, but it’s not bad to have a late summer bloomer in the garden. The skippers tend to be the most common pollinators on it, but the bees go to it some, too.
