Over the decades the various names of this variety have varied in popularity, as it has many synonyms. This week I discovered an old catalogue entry from W.W. Coles, nurseryman from Kokomo in central Indiana. This nursery was the plant originator (a sport of The President) and obviously the name is now confirmed once and for all as Canna ‘Rosemond Coles’. This also removes speculation that it was originated by Captain Cole in Australia.
The entry in the Canna Cyclopedia has been updated, but the separate synonym lists will not be updated until after Christmas.
