I see and understand your point Michael. Here at NGA we are trying to keep it from becoming too confusing by having the original name with all the information of breed, etc., and a designated 'Also Sold As' with the Trade Mark name in the entry. This is secondary information only.
We don't have any control over what is done by the nurseries, so this is how we handle it so we can stay true to the original name and breeders.
