Has anyone else grown integrifolia seed from Bjornar. I had seed collected in 2014 which germinated very rapidly. Some seed was kept back and sown again this year. Again it germinated rapidly. I also had fresh seed collected in 2015 which failed to germinate at the usual time but I hung on to the pot and do now have a couple of seedlings. The same seed sown this year at the same time as the 2014 seed has again failed to germinate. I am wondering now whether they are actually the same species. Does anyone else share my experience ?
