The North End got shafted in the Pergola design process. No Roses grow on the structure. Clematis grows on less than half of the vertical beams. I have a heard people comment that it looks unfinished. The Greenway Conservancy refuses to plant any real vines on the pergola because they are afraid the vines may have clingy roots. They are preparing today for when the Pergola needs painting 50 years from now. It looks like a remnant from the old elevated highway or a unfinished prefab Butler building frame.
I want to add a painted vinyl canopy to the top of the Pergola. This will provide shade in a park. At the moment the parks have less than 1% shade.
I would also thought hanging flower pots off the poles would be nice.
You can ignore the green ivy in this photo sim its an old idea.
In the end we need to soften this steel structure with somthing.
