Good fragrant climbing / vine for zone 6/7
I want to add something climbing to a fence that borders a SW facing, but shady patch of my garden. There are some kind of evergreen (but leafy) shrubs there now, but I wanted to add something floral and/or fragrant. The fenceline / shrubs face SW but are below a bunch of trees. In the winter, they get just about full sun; when the leaves come in, the fanceline /shrubs get half sun.
I like honeysuckle, trumpet vine and wisteria - are there any disadvantages to any of these? I have read that honeysuckle may emit something that may impede growth of nearby plants?
