Climber in small bed - suggestions?

I bought my house the summer before last and now I've done all of the indoor stuff that needs doing, I'm planning out my little back garden. I'm a total beginner to gardening and I have very little time to spend on the garden, so my main priorities are for plants that require as little knowledge and effort as possible!
I intend to plant some herbs along one bed and have some container plants on the patio area, but I have one bed and an arch that I'm not sure what to do with. The bed is about 2m long and 0.8m wide and has a 2m high trellis fence along the back, and it gets sun in the afternoon. Ideally I want to plant something that will climb up the back trellis, but I don't want whatever I plant to take over the rest of the garden! There's also a metal arch that could either have a container plant on either side of it or something planted directly into the ground. It'd be nice to have something that will stay green over winter if possible. Does anyone have any suggestions for suitable climbing plants? I was thinking maybe a clematis of some sort along the back wall, but I'm not sure what to have over the arch. Anything but honeysuckle, because I already have honeysuckle in the garden and I'd like some variety.
