From my experience, east exposure is the prefered exposure for roses. I should think you are fine with any selection you want, presuming this early am exposure is not blocked by trees or structures? Too, ivy will destroy the bricks in about 200 years. But, I would prefer roses any day!! I am in Texas, so climate is different, and you didn't mention a color. So, I really don't know what to advise you, but I think MANY roses would do quite well. For a great exposure like that, I would be tempted to look at David Austin's roses. Golden Celebration is a lovely yellow that even says partial shade. There are too many to list, but let us know colors and shapes. Enjoy!!

Thanks Dan for the info, unfortunatly, blaze and new dawn both bloom on old wood. Golden Showers looks like a nice hardy climber though, and it blooms on new and old wood. Not sure if I would want yellow though- If anyone else has a few more suggestions for a new wood blooming climbing rose? I have been seeing "Shade Tolerant" in the descriptions of some roses (including the Golden Showers) and I figured that would mean they can withstand part shade. I was hoping this meant it could still do well with 3/4 hours of direct sun a day- can anyone clear this up for me? How tolerant is "shade tolerant" when it comes to roses? And of course, if anyone is growing a rose bush/climber/polyantha in part sun, I would love to know which kind it is. Thanks!

Thank you very much mighaelg, I appreciate the information, and it sounds like you really know roses! I know I have to be careful with my choice, and I'll probably decide to go with the Westerland just to be safe. It's not that I feel like Westerland is a compromise, I just wanted to make sure there wasn't some other obvious choice I was overlooking. I'm not keen to "invite" challenges like blackspot or winter die back, especially since I won't be providing the optimum sun exposure. I really appreciate your input - thank you!

If it is part shade, there are several varieties of clematis that you could try. I have 'Silver Moon' growing on the north side of a slatted fence, under a Heptacodium. It gets little direct sunlight, but still blooms well. This Spring it's had 20 blooms. 'Hagley Hybrid' & 'Nelly Moser' are also recommended for partly shaded conditions.
