When the pergolas in the N. End park were built and planted, I had complained here, and was contradicted. Other posts insisted the vines would jump from horizontal to horizontal and fill the space. That was 2 years ago. I reiterate now that:
1. The species of vine is not appropriate for growing on a steel structure...too delicate, esp.to survive winters. The pergola at Columbus park is filled with wisteria, a very fast growing (even invasive) and strong vine. In fact, when the pergola was restructured last time, it took only a couple of years for the vines to grow back, stronger than ever. Surely the steel of the North End pergolas can support wisteria.
2. I could not believe that the wires for the vines were solely vertical. A mesh is not necessary, just a few interconnecting steel pipes welded onto the frame will be be enough to catch the tendrils of wisteria, or some other heartier vine species.
3. They still haven't fixed the fountain jets, which were supposed to be plumb to the surface and not arcing all over the place.
