Evan, so true about multiple cultivar names for the same plant:
I have Canna 'Bangkok Yellow', 'Minerva', 'Nirvana', 'Striped Beauty', 'King of Siam' - all the same plant; a very old cultivar from Asia. It's nigh impossible to trace back what the original cultivar was, if it even had a cultivar name when discovered.
How are you showing multiple cultivar names?
