I have to agree with Mike A fan can't rebloom if it hasn't already bloomed. I've never heard of a left-over scape. my scapes turn brown when done blooming if no seed pods are present and even with pods when they are ripe the scape turns brown and is done. If reblooms nearly always comes from a replacement fans then any good multiplier could be considered a rebloomer. To me these should be called successive bloomers and not rebloomers because it's different fans blooming at different time frames. Even with other plants a rebloom happens on the same plant and not a pup or sucker. For a new fans to send up a scapes it's just stating the fans are finaly old enough to reproduce and would seem to be more common than a 1 fan plant sending up more than 1 scape. I'm not limited on space but if I was I'd rather have a 5 fan clump send up 10 scapes a year then have it make 5 additional fans just to send up 10 scapes especially if that daylily was labeled as a rebloomer. This could be an issue for someone who wants a reblooming daylily but is running out of room. IMHO

Seedfork said:I really like that 'Swirling Spider', but the data base gave no bud count or branching info.
But your photo added to the database shows how important that type of photo can be. I really love it when looking at a cultivar in the database and so many of the photos show multiple blooms and nice clumps!

I purchased a specimen from Lisa this year, looking like a sturdy plant. FWIW. Anticipate much goodness.

Thanks Regina. I commonly get prolifs on several cultivars but none quite so pretty.

Definitely noteworthy.

Being the AHS seems to be the official guide for terms and definitions, I would love to hear from @floota.
Maybe a few more hybridizers could give their opinion?

ediblelandscapingsc,
I agree with you and Mike that a fan cannot rebloom unless it has bloomed a first time, I am just not sure that the AHS rebloom definition is limited to a single fan! I agree with Donald and Maurice also, in my garden any bloom that shows up after the initial first flush of blooms is adding to the length of bloom display and I considered that to be rebloom. I would even consider a proliferation that created a new scape and bloomed to be rebloom,... (proliferation rebloom)?
Now taking my last view to the extreme, if I purchased a plant from a nursery and that plant was a new fan or fans produced by the mother plant, later in the year I went back and bought more fans from the same mother plant and planted those in my garden, they later bloomed? Now would that be rebloom?
One of the main reasons I look for daylilies that are described as by terms like "fast multiplier" is not because I want two dozen new fans to sell (I don't sell plants) I am looking for all those scapes to come shooting up and displaying new "rebloom". The drawback certainly is that you do have to keep thinning out those plants regularly or the clump will become too large. I have seen people specifically avoid plants that multiply rapidly, so how a plant "reblooms" would indeed be very important to them and I think maybe the method of "rebloom" should draw more attention. Single fans reblooming would be a much better type of rebloom for people with limited space.

In iris, that's exactly what is termed a rebloomer. An iris rhizome only produces one bloom stalk. I think it's believed that the timing of rebloom on new fans is controlled by genes and results in several different kinds of rebloom - ever-blooming, summer reblooming and fall reblooming - but all rebloom is on a completely new fan. Most iris are spring bloomers and generally don't bloom outside that time, no matter how well the extra fans grow so the ability of a cultivar to do it defines a rebloomer. I'm more familiar with iris than daylilies, so having new fans produce scapes later in the season and calling it rebloom is an easy step for me.

I am a bit confused by all of this too but no matter which is correct, I'll definitely take the extra bloom time any day.

@Seedfork I think part of the problem may be the biological situation and the apparent visible to the gardener situation.

The description below is based on how biologists have classified the way daylilies develop scapes/inflorescences.

Biologically a fan of leaves is produced by the growing tip, the shoot apical meristem (SAM). In daylilies the seedling begins with just one SAM. The basic sequence is for the SAM to produce a number of leaves and then to produce a scape. While producing new leaves the SAM stays the same size or grows larger. When it produces its scape the SAM grows smaller and becomes all used up in producing the stem, branches, leaves, flowers, etc. of that scape. Once the fan has bloomed it is finished. Its SAM is gone. The crown is able to produce one or more new SAMs from the axillary buds that can be found or are developed in the angle between each leaf and the crown. The crown of a daylily is a compressed stem. A new SAM produces a new fan. A new fan can bloom in the same growing season. That is rebloom. The new fan(s) that are produced after the SAM becomes the scape usually appear immediately beside the scape and between a leaf one side and the scape on the other side. Biologically one scape, one SAM, one fan. To produce a new SAM and new fan and a second scape, an axillary meristem is promoted to be a new SAM.

In some cultivars, in some locations and under some growing conditions the new fans do not develop very quickly and one can see that their SAMs had become resting buds for a short time (presumably when a SAM becomes a resting bud the outer leaves of the bud become scale-like). Then one might be able to see that there was a new fan developed from a bud.

In some cultivars, in some locations and under some growing conditions the new fans develop rapidly (they probably overlap considerably in development with the scape) and one cannot see any evidence that their SAMs ever became resting buds. It looks like there is only one fan with a scape lower down and another scape further up. There are no obvious differences in length or width between the leaves below the first scape and the leaves above it and below the second scape.
=
There is an alternate explanation for how daylilies flower that some biologists consider explains the situation when it appears that two scapes developed on the same fan. In this case the fan is assumed to have developed its first (lowest) scape from an axillary meristem. That allows the SAM to continue to produce leaves until it finally becomes the second scape.

I suspect that may happen as an accident of development very rarely. That is why basically I consider that all rebloom comes from new fans, biologically.

Maurice, so in simple terms on my level, you are saying the great majority of rebloom should be credited to new fans, and only a very small percentage at best should be attributed to reblooming (more than one scape per fan) single fans. I think I have that right. So in that case it would seem to me that the AHS definition would not be referring to single fans reblooming but to the sequence of the plant creating new fans and new scapes throughout the season? But also including the dual scapes forming from a single fan.
Thank you so much for your input!

I counted over 30 varieties "reblooming" in my garden this morning. I will just show a few. The total number of blooms each morning is way down now compared to what it was.
I have several clumps of 'Jolyene Nichole' that are doing well, it has been a good plant for me. It is low but multiplies at a nice pace and has a beautiful bloom.


'Buttered Popcorn':

'Apple Tart': Was slow getting started but doing much better now.

'All American Chief': The raccoons have been digging all around it lately so it is caged. Planted in the spring and is doing nicely.

Yes, you do.

AHS dictionary definition for reblooming http://www.daylilies.org/ahs_d...
"REBLOOMING, RECURRENT, REMONTANT: Having more than one cycle of flowering per year. "

But also including the dual scapes forming from a single fan.

Yes, it includes both.

Thank you so much for your input!

You are welcome.

Majestic Hue



Leebea Orange Crush



Lavender Vista



Silver Veil



Always Afternoon



Bud builder Final Touch



Here is today's rebloom. My biggest surprise this year has been Silver Veil. Original scape had 5 way branching, large flowers always had plenty of room to open. On its first flush Silver Veil was colored like the picture of Majestic Hue. I included one of my bud builders Final Touch. I was surprised when I saw it today. I thought it was done and it looks nothing like it normally does. Normally it matches the database pictures, but is less pink more peachy. May the blooms in your gardens be abundant and may the Son shine on you!

Reblooming her this morning in between thundershowers:

Hold Your Horses


Crimson Reflections on two fans


Janet and Bill on two fans


Aztec Headdress - This one has rebloomed reliably each of the six years I've grown it.

I'm sorry if I hijack this thread, but since many mentioned new growth and new scapes behaviour I'd like to know what these can be called: mini fans growing in the middle of old fans. I hope you can see from pictures!

@cybersix
Sabrina,
I think that is just how daylilies make more fans and thereby eventually making a clump of fans. I believe these are growing from buds down in the crown that is growing the main fan. I just consider these increases. By the time another season arrives, they will just be full sized daylily fans which will probably be producing bloom scapes.

I agree, it to me it just looks like the fan is dividing and creating new fans.

with Donald and Larry...

I have 'Lake Norman Spider' that is doing this too, but do not have a photo handy. LNS however has a scape formed and coming up between the two fans.

Thank you, I never saw new fans inside old fans, or I overlooked until now or all the new fans were coming from the side of the old fan. But this year is the year in which DLs are really growing and blooming like crazy, so surely I'm just seeing something normal but new to me!

A beautiful bloom this morning on 'Red Apparition':

'My Path':

'Lime Frost':

'Bela Lugosi':

'Mary' Gold':

'Optical Delight': This first bloomed on April 15th 2016 and has been blooming ever since. It makes me want to try spreading a little pollen around every time I look at it. I have resisted so far.

What a year! I have never been blessed with sooo many blooms before!
Corryton Pink : Huge crisp bloom





Bridgeton Invention : Huge bloom really can not tell the difference between the first and reblooms.






Daring Deception: No Deception here. A steady performer.


Happy Returns: What can I say, scattered throughout the yard, you can always find one in bloom! If that's not Happy I would not know what is.



May your gardens be blessed!
