Thanks Evey! Prince Charles looks like a perfect one. Princess Diana is really interesting, but I read where it can have a problem with mildew, so I may have to think of a different location for it with a little more airflow. Artic Queen is one I think I'll have to find a place for too. And while I was looking these up I ran across Avante Garde. Like that one too.
Right now I'm trying to get an Aristolochia vine under control along my chainlink fence. It was fine for a few years, but has now become very invasive and is shooting up sprouts 8 ft away. I worked on killing it last fall, but think it will take a few more years to get it under control. Hopefully then, I will have a lot more room for clematis.
