Thanks for the reply, and sorry it’s not the best picture. The house is on a hill, with steps going up to the stoop in the picture, and the concrete stoop itself is about 4 feet high. There are already three young endless summer hydrangeas in front of the stoop (in the first picture, they are just outside the range of the bottom of the photo), and some other mature perennials as well. The right-hand side of the stoop, where the wisteria grows, is not as visible, so it’s not urgent to plant something in its place.
A vine on the railing would be nice but not necessary. I was thinking a clematis would do well there, since the spot has a shady base and gets lots of sun on the railing itself.
So, you think I should try to rid myself of the wisteria? What’s the best strategy? I read today’s blog post, about your unkillable plant, with interest.
