I want a climber, preferably evergreen, reasonably quick growing, for the side of the house (including the not-so-aesthetically pleasing extension). I have got cold feet over ivy - had thought about Hedera...Gloire de marengo, and boston ivy (too rampant?), but the current favourite is Clematis armandii. Anyone have experience with this, what is the best way to support the clematis?
