Trachleospermum jasminoides - as long as the situation isn't too exposed.

Clematis cirrhosa - there are several - I like C.c 'Lansdowne Gem' best, but there's also 'Freckles' 'Balearica' and 'Wisley Cream'. They flower in the winter, so they're great to have around.

You could always plant another Clematis with it for summer colour as well, but make sure it's a group 2 which doesn't need pruning.

Or Clematis armandii, this flowers in spring and has elliptical evergreen leaves and doesn't need regular pruning.

Thanks for your answers these are all very helpful better get down the garden centre and see what i can find. thanks again
