Hi Myriam and thanks so much for the photos! That's definitely it! I was fascinated by the fact that there was a line of these all the way up my rocky, gravelly driveway and they were (unlike Sympiotrichums and Solidagos) seemingly untouched by the deer or resident woodchuck! I transplanted some and have been watching them closely....there are flies and bees all over the neighbouring asters and goldenrod but NOTHING comes near these soldiers! Have you seen anything eat or take nectar from them?!
