I've got 4 clematis on a north-facing fence and they're all doing just great. Here's two of them
Clematis alpina Pamela Jackman
Clematis H.F. Young
both on my northfacing fence, planted the previous year.
Lots here that are happy in shade http://www.taylorsclematis.co.uk/clematis-will-tolerate-shade/
