All sorts of clematis and one or two roses will like it as long as the soil is generously enriched with plenty of well rotted garden compost and manure and handsful of pelleted chicken manure or blood, fish and bone for good measure. You will also need to attach panels of trellis or stretch training wires along it at 12 to 18 inch intervals to support them.
You can cnsult this website to search for clamtis which like a shady aspect - http://www.clematis.hull.ac.uk/ or consult a specialist grower such as http://www.thorncroftclematis.co.uk/
For roses, have a look at Guinée, Mme Alfred Carrière, Zephirine Drouhin, Golden Showers, New Dawn, Souvenir du Dr Jamain. No doubt other posters will know a few more.
