every clematis I have had is a climber, a grabber that likes chain link fences and wires, they usually grow about 6' wide and up to 10' tall with support ( I have seen them go right up to the roof ) they like their roots shaded, and they are usually a mid summer thru fall bloomer, but some of mine bloom in the late spring thru early summer, lots of blossoms on established plants, and will need pruning back every so often, one of my favorites :)
