I think those posts can be seen in:
The thread "Rebloom in the North" in
Daylilies forum Maybe
@Wildbirds will see this and give more information on how the system works. Seems odd to be able to trademark a plant that has been in commerce for a while and has already had distribution before the TM. I can only grasp that the same daylily is being offered with two different names. I'm not clear on the process beyond that. I think, also, that more than one commercial entity does this. I'm presuming that the company that has put the new TradeMark on Ruby Spider and added a prefix name could prevent another company from using the same plant. It's not good to be presumptuous, though.
