Hoping for some advice. I have a damp spot (I'll try to add some fill) that is in dappled shade, no direct light all day. I hoping to use a Clematis there as a privacy screen. Zone 3. The bigger the better. I'm thinking my best options are Jackmanii Suprema or Polish Spirit? Would one be better suited? I like the dark blue purples but if there's something hardier and quicker to grow I'm open to any suggestions.
