I'm building a new deck with a pergola over part of it. About 12' of the pergola will be attached to the house so I am not real excited about growing vines on it, I'm worried that the vines will go to work on the house. What do you guys think about some hanging basket types with creeping plants that don't root? Does anybody know one that will grow fast enough to provide shade before my 3 year old goes to college and I down size? I live in Atlanta (zone 7).
