Winter jasmine will need tied in as it doesn't climb like summer flowering varieties. I have it and love it but it can become very bushy and needs cut back after it finishes flowering to keep it in shape and space.If you grow something else through it, you need to be aware that pruning lay well be difficult and you may prune the wrong bits!
There is an evergreen variety - Trachyospermum jasminoides AGM-star jasmine. It flowers in the summer, climbs and retains its shiny leaves. It needs a sheltered, sunny spot.
