Yes its my opinion that they should remain separate. My Black Cardinal, Prince of Orange, and McColley's finale are all years and years old before all this nonsense started. They are still the original hybrids, just with some added new name to try and sell more plants. My Thai Constellation was from a local grower in like 2005, my Albo Monstera, same.
It MAY be the same thing that happened with Alocasia reginula, Anthurium luxurians and Alocasia Amazonica way back in the wayback. They went into tissue culture, and Agristarts selected out one 'special' cultivar to prop and move forward with. A. reginuma became Alocaisa 'Black Velvet', A. lux became A. lux 'Quilted Heart', and A. Amazonia became Poly. They were able to TM those, but because these plants were all originally species (or in the case of Amazonia a natural hybrid) they couldn't;t patent them. But they were able to attach a new name for market.
They do the same with cannas....Tropicanna is the TM name, and the other names of the various ones are the cultivar names.
I think they do this because they think that there are a lot of 'new' houseplant people emerging every day who have no idea of the history of these hybrids. SO they think they are getting 'something new'.
