I have just bought a clematis armandii having seen the superb specimen
on my daughter's house wall.
Our walls at home are already covered with treasure trove, Campsis mme
Galen and various others so I thought I would like to grow it up a
tree.
It seems pretty vigorous has anyone tried this. I am thinking of an
ash tree?

Looks from clues in your posting you might be in Wales! C. armandii should
love it :~)
To get it into something large like an ash tree start by planting at the
edge of the tree (not at the trunk) create a plant ladder from some wire
well anchored at the ground up to the branches and make sure you water well
and reguarly May to August this year (regardless of the weather) once going
you should have no problems (they look stunning when grown in trees like
that, I only wish I could grow the trees!!)
