I'd like to use clematis on a lath fence I use to shield my work (read that mostly junky and unorganized)area from where we sit. The fence is right on the drip line of a medium sized walnut so will be eventually 'within' the dripline. Are clematis sensive to the walnut's juglones (hope thats the right word)?

Another option would be putting the clematis in the half barrels I have in front of the fence, but wonder if they would winter over?

Thanks for sharing your experience.
