Every year I have at least one new question concerning daylilies.....

This year I am wondering about "rebloom". What defines a re-bloom of a cultivar?

I suspect this one is just a continuation of first blooms, but because the original first scape is already brown, I began to wonder if it may indeed be rebloom.

It first started blooming around June 25. Only had 4 buds which finished around June 28.

Now it is July 9 and there are 3 more scapes. The plant has 4 fans, and currently 3 scapes with the 4th scape already brown.

So is this just a continuation of the first round of blooms or is it considered re-bloom scapes?

We have discussed rebloom before and we were given a very technical version of it. My version is a little simpler.
I think the main question came down to: Does rebloom have to come from the same fan to be considered rebloom.
Some thought it did, some thought it did not.
If I have a clump of a cultivar that sends up new scapes after the original flush of scapes, then I consider that rebloom. Most of my plants have become far too crowded to be able to try and determine if the scapes are coming from the original fan, and I certainly don't think the growers are looking to see if the new series of scapes are coming from the original fans. I think they are just looking for a second, third or fourth series of scapes ...to me that is rebloom. I do consider crowns that produce a series of scapes also to be rebloom, but with all the cultivars listed in the database as rebloomers I don't think that is what was observed.

AHS defines rebloom thus: Remontant, or reblooming at intermittent periods.

Some time ago Daylilies were often listed or described as recurrent. Remontant means achieving successive yields within the same season. Recurrent means happening again and again.

I prefer the term recurrent as it allows for rebloom to include secondary clump blooms such as you describe. The second set of scapes emerging from fans that matured into bloom later than the original bloomer.

Last year I had Carousel Princess bloom on one fan at its normal time (it just started blooming today). Then in Fall (maybe September or October) a different fan grew a scape that bloomed. I was told this is considered rebloom when I asked about it.

@Ammad gave a long explanation on this subject last season. You should be able to go back under rebloom title and find it. One thing is clear about this single fan of My Cup Overflows. It has instant rebloom.
