Looking for suggestions, and I know you guys will have a million and one ideas.

I live in SW Michigan, zone 5b, my front yard faces south west and gets full afternoon and evening sun. I have two mature hard maple trees and quite frankly the trunks aren't all that pretty. I'm a rose lover with limited sunny space in which to grow roses, so the logical solution is to make the most of this opportunity and grow climbers :)

My house is white, all of the roses I currently have planted are pinks and reds, other perennials tend toward pinks and blues, but I'm a scavenger and have accepted more than a few donations ... so who knows what will come up this year :)

In short, I'm looking for something that is cold hardy to zone 5, will take well to growing up a big tree trunk, likes tons of sun and the less maintenance it requires the better (I can manage feeding and watering, but I'm not a fan of spraying and constant pruning and dead heading) I'm also open to clematis/rose combo suggestions :)

Oh and roses that I currently have planted on the side of the yard where the trees are; red parade mini and Abe Darby (the HT's didn't make it). On the other side of the yard I have William Shakespeare 2000, Jubilee Celebration and Bishop's Castle.

Thank you and advance!
