I second Ghislaine for health and vigor. I have seen Buff Beauty cover an arch pretty robustly but mine declined in too much shade. I saw Gloire de Dijon nearby and it was full of blackspot. For me Crepuscule is a strong growing, healthy plant and it's mostly cantaloupe colored here. Mine declined due to encroaching River Birch roots and baking hot , dry location. We get very little mildew here so I can't comment on that.

Maybe you would like Golden Century, climbing mini. See Paul Barden's pics of it here or on hmf. It seems to have enormous vigor and so far here it is very healthy. Got one about a year ago.

Crepuscule when it was doing better with Pat Austin in foreground:

This Crepuscule grew in a large pot and got morning only sun. It is a paler color but still apricot to me.

Ghislaine....not as peachy to me:

Another one with great vigor and health is Alister Stella Gray or Grey. I have seen a pic of a huge one growing in England...guess it takes some cool weather and grey days.

It's not peach but yellow and white.
