ShakespearesGarden said:A further note about asexual propagation- those patents are only good for 20 years past the introduction year. If they are Stella babies, chances are those patents are expired. Check the registration year in the database for each variety...
As is often the case with a plant patent, the cultivar name patented is not the one that is used in marketing.
The one in the link above is being marketed under the trade designation EveryDaylily® Yellow Punch but the actual patented cultivar name is 'VER00204' (Plant Patent #26,906).
Looking this up in the US Patent database gets you this descriptive page for it:

The date on the patent is 2016 so this is quite new. It looks as though it is registered with the AHS as 'EDL Punch Yellow' (2015), at least it looks the same and the name is similar to the trade name. Also has EveryDaylily on the AHS pic:

Edited to add, I'm not sure how this works because presumably a plant cannot have two valid cultivar names and the one dated first should be it.
