There are several plants it reminds me of , The bloom buds developing resemble aster (roadside wild) The serrated leaf edge are the only thing keeping me from being sure it is Wild Spurge , But I have never seen the Wild spurge either
I have a pink and a blue Campanula , one possibly from you , this is interesting though There is a small chance it could be though
Cindy The Campanula Saxifragia are a match also
Really need to see blooms
