Clematis or ? in a planter?
We have built a deck this year and my DH is going to build cedar planters and an arbor as the entrance/exit to steps to give it some 'character'...as opposed to a 'box' on the back of the house.
I would like to plant clematis or some kind of flowering vines in them. He is going to to line them with styrofoam and I would like some suggestions as to what would overwinter in a zone 5 garden under these conditions.
This is on the south side of the house and gets full sun.
Any advice would be greatly appreciated.
