Hi! Sorry to hear about your finicky Climbing Peace. I as you know have a love-hate relationship with mine...I love it when it decides to bloom, but hate it at all other times, which is nearly always. It is a blackspot magnet without equal and and a finicky unpredictable grower, sometimes doing nothing for a long stretch and then shooting up a 6 or 7 foot cane in what seems like days, then there is the cane dieback that pops up now and again. So, on to more worthy climbers... If you don't mind a once bloomer, one gorgeous creature is Alchymist. It produces a good amount of blooms on an established plant and the blooms are absolutely gorgeous. Just don't plant it where it would be exposed to intense sun such as a southern or southwestern exposure without some afternoon shade... a western exposure is fine as well as an area with overhead afternoon shade especially in the summer. Given that and minimal care it should satisfy if once blooming is ok.
If you prefer a repeat bloomer, the super hardy William Baffin should be a fine choice. It will take zone 6 without flinching. It can be grown as a large arching shrub, or a climber if you wish. Others I've heard good things about but do not grow and have no experience growing are Golden Showers and Altissimo. I have seen Golden Showers in other gardens and must say, it does look pretty!

I take your side! Pehaps you can replace it with something more productive and to your enjoyment. I have had only three blooms this spring with so far not a sign of another flower bud, but it has sent up yet another large cane from the base, as has yours. I had no blooms last year. The point of roses is not simply for foliage, but for the flowers they are famous for. Perhaps you can remind him of that and he might agree to a suitable replacement. Best of luck!!!
