Hi Percy (love the nickname)
You've had some great answers here so I won't bother to add the same info but have you thought about growing your clematis through a boring shrub? You get the protection from the shrub and if you choose well you can extend the interest of an exstablished flowering shrub. You can also combine the flowering times to make a stunning display. I have an alpina clematis growing through a philadelphus, a montana through a dull conifer and a President (dark purple) through a Gertrude Jekyll rose(rich bright pink) in my Glasgow garden.
