I think they are real daylilies and that they are all linked. I think they will all soon have new roots.
I potted up almost 40 proliferations this year. Still occasionally finding one now and then. I started on August 25th and potted them up in mostly trade size gal. pots. So today will make one month since they were first potted. After I take my wife out for lunch today I want to get back and unpot a couple of them and see what type of roots they have. The last I looked I think I had finally lost one and another one was not looking too good, but I was thrilled with that.
