i feel my plant much closer to the references (bouton très allongé/journal des roses) of mme cunisset carnot than the plant at l'hay pictured by amiroses.
on the other hand,the starry outline of its blooms makes me think of another variety: mme emilie charrin with its frizzy blossoms, the proliferation often seen on my plant being obviously caracteristic of that variety. i guess that a mixup has happened.
