As you can see it is an exuberant vine and constant trimming is necessary to prevent it covering the front door. ( I have seen a few front doors like that over the years) The original wooden trellis attached to the wall broke under the weight last year and there was grave concern over what to do; tear it down and replant or try to salvage? Finding a new one would not be easy as the only one I ever see is the white Confederate jasmine. David drilled into the wall on the side and tied it back with a piece of hosepipe. It was touch and go there for a while because the green hose and the wire attaching it to the wall were quite unsightly. But within a year it had completely covered the hose and now, as I look though the window, I am appreciative of David's fix.
Although growth is similar in that it is a self twining plant and reasonably hardy in central Texas, the flowers are yellow and more exuberant and I do find this one to be hardier than its cousin.
Compare this with the pure white flowers of the white confederate jasmine.
Despite its location on the similar NW facing wall this vine was severely hit by our winter freeze, all its leaves turning brown and many of its stems splitting. However, after pruning and primping, it has made a good recovery in recent weeks and is now flowering. Like the other jasmine it is constant work to keep it in its place.
Both are favorites for maintaining an evergreen look over the winter even though they do take work.
