I would not use Hydrangea petiolaris as others have suggested because it is deciduous and grows very slowly. If you do want to use a Hydrangea try the Mexican one called H. seemanii. The flowers are identical. But it is evergreen and grows a great deal quicker than those mentioned. But it too takes a couple of years to get its roots established.

My 'how to build a palisade fence' page does exactly that. I use mine for clematis (I have a 100 varieties).
