I have a Madame Plantier Rose that is appromixately 5' tall and has no buds. It gets full sun and I keep the soil moist. My other roses are blooming and have been since June. This rose was planted at the same time. I am stymied becases I can't figure out why it isn't blooming. I also have been fertilizing with Schultz bloom pus (10-60-10). Please could you give me a suggestion on what to do,

As I understand them, Mme Plantier roses like partial shade. I've even seen one site mention they like dappled shade.

Mine does fine when in pretty deep shade, but its colony of PM also thrives. PM pressure here is intense, and it's probably a different strain than what most of you have, but depending on where you live, you might want to leave it in a pot at the intended location for a while, and see whether it stays healthy.

Can you explain what PM means? PM pressure? Thank you. I am deciding on a spot to plant Mme Plantier.

Probably powdery mildew. I wonder if the OP ever got her rose bush to bloom.

Thank you! Makes total sense, fortunately I do not have that problem but suffer from RRD….rose rosette disease. Ugh.

I do hope that you are destroying (best by fire) any specimens you discover with the disease. You probably know it is incurable, and contagious to other roses.

Yes, I am unfortunately aware of that. My roses are just beginning to break dormancy and so far so good. Too early to tell yet though.

This is called proliferation. Cells in the center of the rose are "malfunctioning" and producing new growth instead of the reproductive parts. The reason is not quite clear. There are many statements that a period of cold in spring can induce such growth, but this is not proven. Here is an explanation from the website of Apuldram Roses:
https://apuldramroses.wordpress.com/2012/05/21/rose-proliferation/
We have had it in our garden with 'Asta von Parpart' where 99 out of 100 blooms proliferated! There are reports of this phemonen since the 1760's, the rose called in England 'Childing Provence' (as it produces children) or 'Rosa provincialis prolifera'. Redouté painted a well-known picture of this rose:
http://rudolfshistorischer-rosen-park.blogspot.com/2013/07/spiele-de-natur-proliferation.html
I suspect that the gene structure of Centifolias has elements which encourages proliferation from time-to-time. Remember that also "moss" started on centifolias. With centifolias then being hybridized into further classes, this tendency apparently got distributed further. It is relatively seldom with repeating roses, and only with the first flush.
What to do? Some break off the proliferated buds so that the strength of the rose is not lost on "deformed blooms". With once-blooming roses, this may of course mean that you loose that year's bloom. The reports I have seen are that usually the following year's bloom has no proliferation. We did part part, left some as curiosity and broke off others.

Jedmar,
Thank you so much for your explanation. I understand now. Your response was much more helpful than anything I found online.
Sorry for the confusion with the photos. Sometimes this website is hard to navigate.
I think I am going to cut all the blooms off. There was a rose nearby that had Rose Rosette and I thought this might be a cause, but the blooms look much different than RRD. It is a pity as Desiree Parmentier is really beautiful when it blooms “correctly”.

Jedmar,
I am very happy to tell you that my Desire de Parmentier bloomed without proliferation this year! It did quite well and I almost didn’t recognize it as it had so many blooms. It is still young, but I am happy to know that the proliferation wasn’t a death knell. We had a mild winter, no snow, so it is quite possible that a cold winter preceding bloom could have caused the abnormalities. Thank you again for your help. I hope you are having a wonderful rose season. We did here, despite a prolonged drought that ended yesterday.

My 3 years old Gallica Officinalis has just started blooming, and the roses are light pink this time around ??? Has anyone ever experienced that, and what could have caused it? I couldn’t detect any smell in the flowers, and they look just like the Lyda rose flowers...
If I hadn’t seen it bloom the pst two years, I would have assumed that this rose had been mislabeled, but it clearly showed all signs of being a Gallica Officinalis.... until now...

All of the buds on my Desiree Parmentier are deformed. Does anyone know what causes this?

It would help diagnose your issue if you would please post photos of how they are deformed.
