I've grown all except Félicité Parmentier in my Swedish zone 5b. I liked them all, still have them except The Fairy which I liked the least because it didn't drop its petals cleanly and on such a small rose it became too unsightly. I should add Ispahan if I were you. It flowers quite long for an once bloomer. Madame Plantier is rather floppy with thin canes so I've made a simple trellis for it. It can be grown as a free standing shrub if you have enough space.

I've only grown The Fairy & Mme Plantier & MMP is one of my top 5 in the garden, I have 73 roses. She is marvellous, she is about 7x5 after 3 years in the ground in partial shade, clean foliage & a blooming machine for about 6 weeks. She also looks great when not in flower. I have her engulfing a large pole with no other support. I tossed my 2 The Fairy because they blackspotted badly even after 4 years, her flowers come in small trusses & look charming adorning a gift. Like Marianesse I found her messy & was constantly grooming her & she rewarded my efforts with blackspot! I do miss those charming sprays of blooms though but would not buy her again.Another good rose, a jolly giant is Darlow's Enigma, flowers a long time, no disease issues & repeat blooming with a nice fragrance, I wouldn't be without him.

Cardinal de Richelieu gets cruddy at the end of the summer if it isn't treated with a fungicide. Not quite blackspot, but anthracnose.

Thank you for your feedback. Mme plantie is definitely at the top of my list. I was on the nice about the fairy. I know it can be quite thorny,

mariannese, I actually forgot to put Ispahan on the list, but that was on my mental list so I am glad you mentioned it.

As far as your garden is concerned, what other plants do you have blooming after your once bloomers are done?

I had The Fairy (6a here, Pennsylvania mtns) and she blackspotted, froze, and eventually was removed because I got tired of her hassles. In town (about 800 feet lower), The Fairy does pretty well in front of several of my apartment buildings. Her vicious thorns keep people from messing with her, so that is also a bonus.

I had Madame Hardy and she lasted (healthily) several years until a low-snow-cover winter with wind and she was like "Nope, I'm out." You may be a bit more temperate or have a less windy location, so... she is a lovely, delightfully fragrant and attractive rose. If you can grow her, go for it.

Madame Plantier did better for me than Madame Hardy but she eventually gave it up too. I think she might have persevered had I been able to give her more sun. Worth a try.

I'll second a vote for Ispahan (clean foliage, vigorous and hardy, kind of blowsy pink flowers and a boatload of 'em, nicely scented) but make sure you have room. He gets huge and (in my yard) benefits from some support.

Also, I've had Charles de Mills for about ten years now. He's awesome. He is reliable and healthy and vigorous and lovely. (And he suckers. Fair warning and all.) Give him a try.

My "rose management program" is "no spray, hack off the dead parts, put 4" of aged horse manure* around each bush once a year." Like, that's the entire program. Roses either live or die in this environment. Ispahan and Charles de Mills are living large.

*There is nothing magical or especially good-for-roses about horse manure. I have horses, is why I use it.

Have you considered any of the larger shrub or climbing polyanthas? They're generally pretty hardy, some have fragrance and all have a lot of charm.

I grow and like all your choices except 'The Fairy', and my not caring for it is a matter of personal taste. I can't comment on disease resistance since your conditions are different from mine. Do you want tallish roses? N.b. my 'Mme. Hardy' is very floppy and, of this group, one of the more disease-prone kinds. How about 'William Lobb', a purplish Moss that grows tall (and might need some support)? A tall-growing Gallica with a great color is 'Violacea'/'La Belle Sultane'; it's a deep red.

I grow remontant roses, modern shrubs and floribundas that flower after the once bloomers. I use lavender, nepeta and hyssop as edging. I get color impact from Italian clematis, the viticella group, grown on many of the old roses that have finished flowering.

Have you considered Celsiana? She can be a beast, when she gets going (even in zone 4) but so lovely! Not my picture, but very similar to ours, right now.

For something that blooms all summer long and is about 4x3, take a look at Pink Pet. No disease at all and is not bothered by my winters at all (several mornings at 10 degrees with 20 mph winds). Grow it on it's own roots and you will have a hard time killing it. VERY easy to propagate.

For plants to bloom after the spring flush I grow Salvia, late blooming iris, daisies, balloon flower, clematis, liatris, aster, daylilly, hosta, ornamental grasses, Hydrangea and sedum and a few more I cannot remember the names of. I have mostly once bloomers but for reblooming roses I grow Mary Rose, Seafoam, Rosarium Utersen, Mountain Mignonette, Darlow's Enigma and Ghislane De Feligonde.

Also have some species roses that bloom later in the summer and form ornamental hips.

By the way Darlow's Enigma makes a beautiful, problem free shrub with a strong scent.

Gallicas do very well for me- no fuss. Carol's favorite gallica is nice and gets rather large, but suckers...

The Fairy never tops 4' here; it's a chore to deadhead but is very healthy in hot humid SE VA (8A) and repeats well.

Mme. Plantier forms a beautiful mounded shrub; very wide. Much different habit than other albas.

If you love beautiful mauve-y purple tones, Charles de Mills is one of the best gallicas.

Felicite Parmentier is to die for; blooms as beautiful as Mme. Hardy and wonderful fragrance. Maidens Blush makes a nice big bush and the light clear pink contrasts nicely with the foliage.

That's a really good list you got there!!!

Felicite Parmentier gets a good deal of BS here and is runty in my garden. But her flowers are beautiful and the fragrance is one of the best, so I put up with it. Great Maidens Blush seems to have more vigor, though gets quite leggy. Leda has very charming blooms. She gets some "damask crud" but doesn't defoliate badly.

I echo recommendations for Ispahan and Charles de Mills, both very healthy and happy here.

In my climate Madame Plantier is such an enthusiastic and floppy rose that it needs a lot of training to make it presentable, and it needs this work a couple times a year at least. Of all the once blooming OGRs I have grown, it was by far the most work. If you have the space, you could grow it as a big floppy mound. It's not a look that suits my style, but YMMV. Many people prefer the exuberant look.

If The Faun (aka The Fawn) is hardy in your area it's a lovely little pink, many petalled rose that blooms a lot, has that old rose look and has had no disease for me (in my vastly different climate).

Can't believe I forgot to mention Fantin Latour which was a fave of mine in my Ohio garden of old roses, years ago.
