Heidi, there are registered daylilies from crosses of the same cultivar, and possibly the same daylily (self polinated), and they look different than the parent(s). Wish I could name some off the top of my head, but I can't. Maybe someone else can help with that.
I think that the seeds in one pod are siblings, but not identical. I've seen many pictures of siblings that look nothing alike, though the seeds came out of the same pod. I'm not sure what you would call the seeds from different pods on the same scape though. I haven't actually seen that talked about before.
You don't have to wait to register a plant until you have enough to sell it. Many people register them with no intention of ever selling them. I would think that if someone intended to sell them, they would wait until they had a good supply, since daylilies tend to bring in the most money during their first year. It wouldn't "pay" to register it, and then have to wait several years until you had enough of the plant to offer it for sale, because everyone would look at the registration date, and consider it an older daylily. Does that make sense? I may have confused myself!
And yes, if all of the plants are dead from a cultivar, it is gone. Happens pretty often, I think.
