I wonder why anyone would take something with a registered name, give it a made-up name, and sell it.
Seems counterintuitive and counterproductive.
My "Maya Purple" resembles 'Purple Waters' in many respects.
Quite often there is some confusion between a trade name and a cultivar name, perhaps because many sellers and buyers don't understand or follow the international nomenclature recommendations. You are exactly right putting "Maya Purple" in double quotes since it appears it is not a valid (registered or patented) cultivar name. A valid cultivar should have single quotes, such as you gave for the registered 'Purple Waters'. A trade designation is not considered a name under the code of nomenclature, should be written in different type, and have no quotes. Ideally it should be followed by the valid cultivar name in brackets, to give an example
Hemerocallis GOLDEN ZEBRA ('Malja'), or
Hydrangea ENDLESS SUMMER ('Bailmer') but that is often not done and a trade name is wrongly written alone and with single quotes.
