Mardi Gras Parade does not rebloom here, I have had it for years it is a pretty bloom. I use to have Butterscotch Ruffles it did bloom a long time, but here the blooms didn't have decent substance.

My MGP blooms almost all summer, but I am zone 6 so maybe that is why? strange.

Don't know MGP is not listed as a rebloomer on the AHS database.

A very important part of whether a cultivar reblooms or not is how it is being grown as well as where.

If it is in a large clump it will be less likely to rebloom: I think that the size of the clump is an important factor on whether a cultivar reblooms. The more fans in a clump the more of every resource that each fan must share with the other fans. That includes water, sunlight (because of shading by neighbouring fans), fertilizer, etc..

If it is not fertilized it will be less likely to rebloom. To rebloom a fan needs to grow and to grow as quickly as it can. To do that it needs sufficient fertilizer along with water and all the other resources. The growth of plants is often limited by insufficient nitrogen. So sufficient or optimum nitrogen fertilizing is important for rebloom.

Because daylilies are perennials it is also likely that how the plant is being grown this season is not as important as how it was grown last season and possibly even the season before. So it may take one or two (or possibly even more) years of a changed growing condition before the growth and flowering of the daylily is changed. Patience and perseverance are necessary after changing a daylilies growing conditions.

large clumps, fertilize w cow manure tea

Maurice, my huge clumps of Stella and Happy Returns have bloomed like crazy! They were starting to slow down just a bit in the center, but for the most part, the clump size hasn't seemed to slow them down, if any. I was really surprised that they could bloom as well as they did. I gave them no fertilizer at all. Just water, and I probably should have watered them a little more than I did. I've since dug them up and divided, but I still can't believe how many blooms there were, and it was non-stop.

Cow manure probably has about 2% nitrogen. Cow manure tea probably dilutes that considerably. When I fertilize with high nitrogen I use fertilizers that are 24% or 32% nitrogen or I use urea which is 46% nitrogen.

@frillylily How often do your daylilies get manure tea?

@Natalie As my clumps of Stella have become larger and larger the amount of bloom and rebloom has gone down and down. There was little bloom this year and no rebloom. I have not divided them in more than 15 years or fertilized them. They are large clumps and the only bloom is sparse and on the edges of the clumps. The Stella are in beds with other daylily clumps close by. I split off three pieces this spring and they were planted in a new bed. They bloomed and rebloomed.

I would have to guess that your Stella is still blooming and reblooming because there are still resources, such as nitrogen, in their planting location that they have not used up or there are other sources. The central fans in a clump are the first to suffer and fans towards the edges of the clumps can mine new areas of the bed with their roots to get the resources they need. Of course if those new areas of soil are also being mined by the roots of other plants then the fans at the edges of the daylily clump will not do as well.

Maurice, I knew that they would slow down in the middle first, but never expected such great bloom and rebloom toward the edges. What you said made sense though, in that there was no competition for them. Nothing else was planted near those two clumps, and they were probably planted two feet apart originally, but almost touching with I dug them out. They came with the house, so I don't know how long they had been there, but the previous owner said they had been there a long time. The house is about 16 years old, so they aren't any older than that. I suspect that they weren't as old as the house. What a job it was to get them out of the ground! I almost got the tractor out to lift the clumps!

I just did it a few times through the season. Maybe 3?

I know it's another yellow, but Going Bananas is almost continues bloom here, and is still blooming. That and Stella are the only two I have, that I would say have a continues bloom, though, the mid season has the best show for both. I also agree 100% with Maurice, high doses of Nitrogen, and water will drastically improve rebloom, as well as, over all performance.

Mary Reed is a good rebloomer but not as many blooms as Stella de Oro. Another good rebloomer is Pardon Me.

I have never had 'Pardon Me' rebloom; perhaps it might be a good cultivar to try testing by dividing the clumps and providing high nitrogen fertilizer.

@cybersix. Sabrina, very few cultivars beat for performance an offspring of Stella de Oro, which is sold commercially here in big numbers in nurseries.

That is STELLA BELLA.



It is listed as a dormant in the databases but here the subtropics it is a small but vigorous bloomer playing the evergreen.

Mine are flowering at the moment.
