I don't know enough to fill in the terms to add these 2 plants, but I have bought them so I know they exist:

Hemerocallis:
Stella in Red
Stella in Purple

I tried to look these up in the AHS database and the don't appear to be registered (hence they aren't here). You may want to contact California Sue ( @Calif_Sue ) as they may be landscaper/trade names. I know that she entered one for me some time ago (I cannot remember which one it was) that isn't registered but is marketed country-wide with a "recognized" trade name.

That was the reading on the tags from HoDepo.
I searched "stella" on the AHS site and found nothing with a picture.
I'm going to mail Sue to pop over here.

I just remembered that the one she added to ATP's database for me was Ruby Stella. Although it is well-known in the trade, it isn't registered.

Yep, these are just landscaper/nursery type names, more descriptive actually as everyone knows Stella de Oro daylilies so they just added a color description. For instance, Stella in Purple can also be listed as Purple Stella and Stella Purple and they can be totally different plants, not even related to each other. They are just names added to plants to market them to the general public. If you have images, you can add them to the general daylily entry.

I'll have pictures later.
So there's a "daylily" form that will fill in all the genus family species info for me?
I'm a hands on, trial and error gardener, not horticulturally educated....

Thank you, Sue

Here is the general daylily entry Daylilies (Hemerocallis)
you can add your images to that.

MERCI!
