There are clematis that take less than full sun and do nicely. Deer resistant I don't know about, but I recently planted around a neighbors mail box that sits on the side of our property. I planted three hosta,Sedum- Autumn joy,a bleeding heart, a day lily, perennial geranium and a burgenia. I was going for plants that will survive on the water nature provides.

What about Geranium Rozanne? It's not a vine, obviously.
