Maigold - an outstanding climber with excellent disease resistance.

Maigold looks gorgeous but probably won't grow in my region.

I'm thinking about Quadra because it's such a vigorous climber and I want something cane-hardy so that it will get big enough to cover the house.

What I really want to know is weather or not this is a reasonable possibility. Most nurseries list it (and pretty much all other climbers) as topping out around 12'. Is this true? I've seen several pictures of Quadra that look like it's growing much higher.
