I have a beautiful, very sturdy pergola on the back of my house. I had a three-year old climbing rose that developed rose rosette disease. I'm having to cut it off the pergola and trellis, not a pleasant job. I was thinking of putting something else in it's place as RRD is common here. I was thinking wisteria, but many have discouraged me because of its weight and what I would have to do if I needed to repair or paint the pergola. So, what do you think of an annual morning glory, like Heavenly Blue? I was thinking it would be easy to remove the dead plant each year if I had to repair or paint the pergola. Any help or other suggestions?
