Anyone have pics or lists to share of their best, longest-blooming daylilies? Which cultivars have you seen bloom over the longest stretch in your garden? No need to quantify ... just curious to learn about people's experience in their yards with DLs that had staying power for them. Group hug

A couple of mine, both blooming for at least 2+ months in 100+ degrees under full sun:

MARY ETHEL ANDERSON in my garden is quite incredible in its flowering duration (a friend, who will remain nameless, insists on calling it Merry Ethyl Alcohol). The longest period so far is 9 December 2011 to 17 May 2012, 160 days (>5months). I am confident it will beat that in 2013-2014 having already kicked off on 8/10/2013. I don't believe there has been a day since then when there hasn't been any buds on any of the four clumps. Interestingly, it was a terrible performer until I broke it up into four fans, moved and replanted. Then it just went mad.

If anyone knows of a year after year re-bloomer that will do it in NE Wisconsin please let me know, re-bloom here is few and far between and only Ferengi Gold did it two years in a row, not the last 2.
I have many that are supposed to be re-bloomers but none that actually are
So if any tundra growers have a re-bloomer please share with me

I second that. I rarely see rebloom here. I thought that Karol Emmerichs would because they are advertised as reblooming in the north but so far I haven't had any rebloom.

I have wondered if "instant rebloomers" would give northern growers a longer show of blooms in the shorter summer. I used to live in the northern midwest, so I know how hard it is to get plants that are up and ready early and then bloom until Sept/Oct.

Here are 11 daylilies currently in the database that are said to be "instant rebloomers" ... anyone have experience with them, especially in the north?

Daylily (Hemerocallis 'Crown of Splendor')
Daylily (Hemerocallis 'Elusive Happiness')
Daylily (Hemerocallis 'Fad Gadget')
Daylily (Hemerocallis 'How Lovely You Are')
Daylily (Hemerocallis 'Murphy's Law')
Daylily (Hemerocallis 'Octopus Tangles')
Daylily (Hemerocallis 'Proof')
Daylily (Hemerocallis 'Queen Jane Approximately')
Daylily (Hemerocallis 'Rocket Science')
Daylily (Hemerocallis 'Stealth Bomber')
Daylily (Hemerocallis 'Thanks Mister Wizard')

Gleni - Edge of Your Seat always looks that good here. I can't say whether it would in other climates.

Cindy - I'm surprised the Emmerichs don't rebloom for you. I was going to recommend them to Ed, but if they don't rebloom for you, they probably won't rebloom for him either. I only have a couple of Emmerichs, Open Door and Wall of Fire, but they both have instant rebloom here.

Tina - I have three on the instant rebloomers list. Fad Gadget has had instant rebloom all five years I've had it. Stealth Bomber has rebloomed every year except last year. Thanks Mr. Wizard had instant rebloom for the first 2-3 years I had it. Now it gets too much shade as the season progresses.

Too cool, Debra! Thumbs up I think I must try and get at least one instant rebloomer just to experience it, and there are some really fun, pretty cultivars that are being mentioned. Hurray!

I imagine that instant rebloom means that each mature fan that sends up a scape, then finishes its blooms, then sends up another scape right away? Do you have to remove the first scape to encourage the instant-rebloom scape to appear? Do you give a bit more fertilizer while it is in bloom? So many questions ... lol.

The ones I have of Karol's that were advertised as rebloomers in MN have rebloomed for me, I live about a half hour from her garden so that may be why they rebloom here. I also have some others that have rebloomed for me, I just didn't keep a record on them. Each year I think I will find time to keep records it just doesn't happen and I already know this year will be the same.
If you want to be happy for a lifetime plant a garden!

I'm in the North, latitude 44 degrees 30 minutes North. Most rebloomers will not rebloom here under normal/typical garden conditions.

But to flower a fan must grow; it takes time to rebloom because the basic sequence is grow a number of leaves and then produce a scape; grow a certain number of leaves and then produce a scape, repeat as many times as possible within the growing season in the location.

To get rebloom the fan must grow as fast as it can. Plants grow more quickly when they receive optimum water, optimum sunlight, minimum competition and optimum fertilizer, etc.

I have done this test with several cultivars now. If I grow them normally they do not rebloom; if I mulch them, water them, fertilize them and keep them weeded they rebloom (It takes a year of optimum treatment to get them to a size that allows them to grow, flower and rebloom well). I have managed to take one cultivar that bloomed only once here to three bloom periods, although the usual is just two bloom periods.

Of course, the longer your growing season then the more rounds of rebloom you can have. One way the length of growing seasons is measured is by the number of frost-free days. Another way is by the number of 'growing degree days' (available from the weatherunderground for most locations). My growing season averages between 1800 to 1900 growing degree days per year.

If you have a cultivar that is registered as reblooming in the North and it does not rebloom for you, try mulching it, watering, fertilizing (with a reasonable amount of nitrogen), weeding, dividing it if it is a large clump, growing it in full sun, etc.

Hybridizers tend to grow their introductions under optimum or luxuriant conditions (so they get plenty of increase). Those conditions are also optimum for rebloom.

It is easy to get a rebloomer to a condition in which it cannot rebloom. One way is to simply let it clump up. The more fans in a clump then the more competition for everything vital (resources - water, fertilizer, light, etc.,). Stella de Oro will rebloom here, but not after it becomes a large clump. The better/quicker the daylily can grow the more likely it will rebloom.

I have been told by at least one Florida hybridizer that nearly all daylily cultivars will rebloom in their Florida growing conditions. They do have a long growing season, but they also provide optimum growing conditions for all other aspects and the plants reward them with multiple rounds of growth and bloom.

Tina - The ones with instant rebloom usually produce a second scape before the first has stopped blooming. So there is only a few days between when the first scapes end bloom and the second starts. In years with heavy spring rainfall, some of these instant rebloomers will start reblooming while the first scapes are still in bloom.

Wow, awesome info. I have started my first-ever application of Osmocote (once in November, once a couple of days ago) and I see even my dormants suddenly peeked their fan leaves out of the dirt to break their winter hibernation! (We're at about mid-60's day/mid-40s to near 50 overnight now.)

I'm sold - at least on doing Osmocote, and we may have found a place to get some horse alfala pellets for cheap. Mild stuff I can hold in my hand or shake out onto the ground is as far as I'll go, but I take heart from hearing how the reblooms may be encouraged by it!

There is no reason to expect prime performance from a daylily without giving it good care. Fertilizer, no competition, water and sun. That's about it. While I do live in FL, I most often get 4 mo of rebloom from my evergreens. I fertilize a lot ..... really, a lot. They are in raised beds in really good soil. Unfortunately they get salt in the air and salt from the irrigation water. Neither slow them down. In the last 3 days, they have just jumped with growth--looking really good. Last year the first scape came up in the 3rd week of Feb. May not be that this year, but I keep looking.

We had the wettest spring on record last year so my daylilies got plenty of water. When they don't get enough natural rain, I make sure they get at least an inch of water a week, which is what is recommended. I might add that our city water is awful, very chlorinated and nothing watered with it seems to do well. I fertilize with 2 different fertilizers, an osmocote type that is a slow release and milorganite. 95% of my daylilies are in full sun. The only competition my plants would have is I have lots of wild violets growing in amongst the daylilies that I have tried for 3 years to get rid of and it is an impossible task. The only pesticide I have tried that works is a vine and stump remover that you have to paint on each violet individually by hand. It would literally take me all summer to do that with the amount of violets I have. Anyway, I have grown daylilies for 20 plus years and have always fertilized and gave ample water and get very little rebloom. I purchased 2 of Karol's to try, Filled to Overflowing and Heartbeat of Heaven and neither has rebloomed. I have had them at least 4 years. I do set lots of pods on my plants so whether that hinders rebloom or not I do not know.

Hemlady,
To reduce the violets I would cover them with five (or ten) sheets of paper and place a shallow layer of grass clippings over the paper to hide it (or other type of mulch). The paper prevents light from reaching the violets and they will die. The layers of paper allow water and fertilizer through and along with the grass clippings also break down quite quickly and help fertilize. Depending on your climate the paper would need to be replaced more than once a growing season.

Weatherunderground gives Metro Detroit as the closest nearby weather station. If you are in a very different microclimate then the next part will be off.

In a comparison over three recent years that I chose (hopefully randomly) your weather seems more or less like that at Springwood with very slighly less cold in the winter and very slighlty more warmth in the summer. There is nothing obvious in the weather that would explain rebloom at Springwood but not at Melvindale for the same cultivars.

Seeds require substantial resources and resources that the plant puts into making seed and making the pod are not put into growth (or storage for future years). Plants also remove resources from dying flowers to put into growth (or storage) so deadheading flowers too quickly will remove some resources (a little) that the plant could have reused. The less resources a plant has then the less potential for rebloom.

Fetilizing:
Usually the mineral in short supply is nitrogen. Usually that is what makes a plant grow quickly and large. When I fertilize my daylilies for rebloom I use 24-8-16 and other high nitrogen fertilizers. I also use urea which is a form of nitrogen. I mulch (paper plus grass clippings) so that the water does not evaporate too quickly and that also helps maintain an even level of soil moisture. A basic rule for most plant species is that the larger the plant the more bloom - for daylilies that does not just mean the larger the plant the more fans the more scapes but also the larger each fan (and its crown) the more buds on its scape. I did check that many years ago by measuring the width of fans at the soil surface, counting the number of leaves. measuring the height of the scape and counting the number of buds. I did this for two or three cultivars. In each case, the wider fans had more leaves, taller scapes and more buds. These were single fan crowns so the width of the fan at the soil suface was an approximate measure of the size of the crown. Last year I did a check of rebloom and the width of fans at the soil surface for one cultivar. The fans that rebloomed had wider fans (and presumably larger crowns). In this case the smaller fans did not bloom at all, the intermediate fans tended to bloom only once and the larger fans tended to rebloom once. Like most relationships in living organisms these types of rules are general, not exact, so one can always find exceptions to the rule. The important result was that when tested statistically the relationship was significant - that is, strong enough to consider real and not a fluke.

When I bought my first daylilies from a daylily nursery I was told that Munson considered that daylily growth suffered if they were not divided every year. I was told that in Florida increase could be 8 to 1 in a year. I have never checked for growth rates in different size clumps but the larger the clump the more self-competition so dividing clumps when they are larger than a dozen fans might help rebloom.

Apps hybridizes (or hybridized) for long periods of bloom and rebloom. In the Daylily Journal number 46, summer 1991 he stated "I really think nitrogen fertilization is very important. I've heard people say let's not overfeed daylilies; that's baloney. Get in there and put the nitrogen on, and get the increase, make sure the water is available. If your other elements are adequate, nitrogen fertilizers will give you the best rewards for the money invested."

In the same article he indicated that he used all-nitrogen fertilizers, ammonium nitrate and urea (with care as they can burn plants). He stated "I guess I would like to warn all growers that complete fertilizers like 10-10-10, used every year for six or eight years, may get you into trouble. You're going to have too much phosphorus after awhile and that will tie up other elements."

Crooks Henley wrote about fertilizing daylilies in the spring 1999 Daylily Journal. In that article she stated (from scientific research on fertilizers for daylilies) "I calculated that if I applied a 27-3-3 at the rates recommended on the bags, I would be applying about 100 pounds of N per year. Most people think of lawns as needing a lot nitrogen. But the daylilies benefited from two and a half times as much! So much for the old adage that daylilies should not be given very much nitrogen. Perry and Adam concluded: 'This genus of herbaceous perennials obviously responds to high levels of ... nitrogen fertility.'"

It is always possible to overdo fertilizing. All fertilizers have an optimum level. Above that level the plant's growth suffers even if it is not obviously 'burned'. With that qualifier, by giving daylilies that have never rebloomed for me (over more than ten years) fertilizer (high nitrogen - including simply using high nitrogen lawn fertilizer at times), water, mulch, etc., I have pushed the growth of the plants and they have rebloomed (the next year). There will be cultivars that rebloom in Florida that one cannot get to rebloom elsewhere (many locations in Florida have 8000 growing degree days [gdd] per year). Springwood over three years had 3385, 3008, 2489 gdd. Metro Detroit over the same three years had 3580, 3250, 2729 gdd. The same cultivar, treated the same way should rebloom the same way in both locations.

admmad, Thanks for providing all that info, others may be aware of it, but I was not. I have always been told nitrogen makes the leaves grow but you will have all leaves and no blooms. If there is one thing missing in my soil I suspect it would be nitrogen.

I put alfalfa pellets in my garden and shrub beds here it makes a huge difference in growth and bloom, I also use Osmocote if I have time to get it done. You should have seen my shrubs that the rabbits winter pruned last year I had plenty of alfalfa pellets and decided to put some in the shrub beds. The results were amazing soon you could not see which shrubs the rabbits had almost pruned to the ground and one shrub that never really seemed to grow well suddenly looked very healthy. I use one of those hand spreaders to put down the alfalfa doesn't take so much time as putting it down by hand.
If you want to be happy for a lifetime plant a garden!
