Hello, does anyone of you have Campanula thyrsoides ssp. thyrsoides in culture? Last year I had Campanula thyrsoides ssp. carniolica. They have grown very well, have also flowered abundantly, with many insects, but unfortunately no seeds attached. Does anyone know the reasons? If someone C. thyrsoides ssp. thyrsoides has, I would be very happy if I could buy the (fresh) seeds :-) I had namely in the "bay" already twice bought seeds, without germination :-( For all the tips Thankful!
