Dawn, Climador is one of the smaller clems. It can easily go in a container or on a smaller orb-type structure. Growing recommendations show it topping out around 4 to 5 feet, but mine has remained shorter because I prune it midseason. I've got mine on a small 3 foot structure in the front of the garden with Bitter Lemon pelargonium growing around it. It makes a pretty display! There is also a Pink Climador that is very pretty, but I've found it is a little more sensitive to our heat. Either one should do just fine for you up there.
Kat, beautiful clematis!!! I can see why you're eager to get started with them. Did you see the article I posted on Clematis for Hot Climates? Dave has given us the tools now, so I'm publishing as quick as I can! =P (Check out the link in the right info box that says "Articles".)
