No, and the reason being is that you can not trademark a cultivar name. Once you register a domain with most (all?) registrars, the cultivar name can be referred to in any publication without restriction. So, if they want to control the name, they give it a meaningless "trade name" that they can make up and even change at their whim.
Anyway, your point is 100% valid. We shouldn't be sorting by "cultivar" any more. We need to sort by the natural referenced name. In some plants, that will be the cultivar and in other plants that will be the trade name. I will look further into how we can address this issue. But for certain, it will involve doing away with "Sort by cultivar" and toward a "Sort by name" kind of thing.
