Hi Sherry! Here's another suggestion... Lady Ashe. I bought my "band" from Heirloom and planted it directly into the ground. It is very disease resistant here on Long Island where the summers are warm/hot and very humid. I have never seen any black spot on this bush. It's fragrant too - another plus. I decided to purchase this rose because the Heirloom website stated it would make a good pillar rose. The canes are very pliable - the wood pillar is a 4" x 4". This was my first attempt at growing a pillar rose. If you look closely (don't laugh), you can see long twisty ties from the supermarket that I used to secure the canes. It's not too bushy so, I think it would be a good candidate to marry with a clematis.
