Can't help with that one Mark except that if it germinated well from the Seedlist, why not wait until that time again? I also received 7 seeds and all germinated, 3 in our autumn and the other 4 in late winter. Previous experience had told me to expect O verna or something less choice than luciliae but I was happily surprised. Mine haven't flowered yet (surely yours were very quick?) but are sturdy little plants.
