Rosette delizzy --- A beauty in SoCal, where it has never rusted or mildewed, in umpty years. Color fades in hot weather, best in cool conditions.

Mme.joseph schwartz -- Lovely rose. Mildews badly here, and also in other places where I have observed it.
But I finally found a clone of Duchesse de Brabant that is clean, so maybe MJS can be clean, too.

Gilbert Nabonnand -- Absolutely wonderful here. The blooms are almost opalescent -- pinker in cool weather. Completely clean here (which means no rust or mildew), this is a rather arching, open plant with great repeat bloom in my coastal conditions.

Grandmother's hat -- A great Southern California rose, useful as a bush, tall specimen plant, or espaliered as a climber. Great repeat. Fragrant, and terrific in a vase. BUT if you have blackspot problems, beware. She can be susceptible.

Irene watts -- The rose in commerce under this name is the Floribunda, 'Pink Gruss an Aachen' (a sport of 'Gruss an Aachen.') This is not to say she's not a great rose, but she is most surely not a China.

Mme Joseph Schwartz - very large plant, very fragrant, love it, no particular problems here in South zone 9.

Rosette Delizzy - nice, doesn't get too large, but susceptible to thrips in the blooms. I like it.

Franzeska Krueger - good rose, I like it a lot. Doesn't get too large. Nice fragrance.

Lady of Shalott is an Austin shrub--golden apricot bloom, very disease-resistant, something like 4x3 (or maybe a bit larger). Mine is only one season old, but I was tremendously excited about it last year and am looking forward to a more mature version this year.

Thank you everyone for your input im so excited to plant more roses I just started adding OGR last year got rid of most of my hybrid teas .i love David Austin roses too even they get some blackspot here so I want more OGR .

Is Gilbert Nabonnand also called G Nabonnand? I have 2 or 3, and they are beautiful.

Louise Odier is one of the most beautiful roses I ever had, but it really only bloomed once -- just like Gertrude Jeckyl.

I have 12 Souvenir de la Malmaison, but Kronprincessin does not like it here. It should, but I have tried about 3 now, and they don't look good.

Rosette Delizy is pretty, but seems a little frail. I need to fertilize it, and see what is wrong.

Gruss aun aachen was very pretty. I had about 3, but they needed spray to survive in my garden, and I don't spray, so they are gone.

Francisca Krueger seemed to have a problem, but I do not remember what it was.

I am just critical, and only have one success in your list. I live outside of Tulsa zone 7A. Maybe your zone 7 is different and you may not have the problems I have.

Good luck.

Franziska Krueger got veggie centers for me, consistently. Maybe you mean Lady Hillingdon. I have a new Rosette Delizy. My previous one was very prone to botrytis. Hopefully, this one won't be.

Have fun!!
