Growing a climber on a downspout?
I'd like to try growing an annual climber of some sort up a downspout on the front of my house. Anyone have any thoughts on this? Would it be safe for the drainage system? Would it be a pain to keep it from growing into the gutters and onto the roof? I'd like to try eith glory vine Tresco Mix or morning glory (Sunrise Serenade variety from SSE).
