If Dr. Pounders is correct that this practice will increase in the future, and I think he's right that it will, then we're going to need to establish a clear policy of how to deal with these.

For sure, the original cultivar name takes precedence as the cultivar, especially when it's been registered at the appropriate registrar.

A trade name will only be used when it is a patented or otherwise protected plant and the owner has given it that name.

Any other names given to it will be in the "Also sold as" field.

I've updated the Canna Tropicanna® entry to follow these guidelines. It is a somewhat similar naming situation where the Canna was initially introduced in the UK as 'Phasion', then Durban and finally Tropicanna by three separate parties. The issue was brought before the EU court which deals with Plant Breeders Rights, where 'Phasion' was upheld as the registered cultivar name. The plant is still a nursery mainstay with the registered trademark name Tropicanna®.
