Training a clematis up a tree

Last autumn, I planted a clematis (can't remember which, something snowdrift?!) which I want to climb over an old elder tree, which looks bare and ugly at the bottom. I have put the following string arrangement in place to train the clematis up. Does it look to you exerienced fold like it'll work? OR do you have better ideas?

 

What you have is C Armandii snowdrift.The support you have put up will be fine, but Armandii is fairly slow growing so be patient. If you want a quick climber then go for one of the Montanas.

 

Damn! It said it was fast growing in the description when I bought it (online). I should have joined this forum earlier, then I could have spent my tenner more wisely.

 

Rosie don't despair hardly anything to do with gardening is a quick fix and I'm sure your plant will look smashing no matter how slow it grows.Hel.xxx.

 

Rosie, I sometimes plant knowing that only my grand-kids will appreciate the end product. And you certainly won't have to wait that long. I think David means in clematis terms they are slow. Not in tree fern terms. :D

 

Oh, good! Thanks for the reassurance. I haven't got any kids who could appreciate my gardening efforts in future years - and the dog'll probably not outlive me! Must try to be less impatient.
