We currently have quite a few vines in our garden which serve multiple purposes. They provide shade, privacy, soil protection, leaves, fruit and vegetables. Here you can see a sweet potato vine and the choko vine.
In the front yard we have a boston ivy on the walls to shade the walls that face the west, a grape vine, a pumpkin vine and a sweet potato vine.
In the back garden we have three grape vines, a choko vine, a virginia creeper shading the eastern wall, a sweet potato vine and a passionfruit vine. They are not only useful but beaiutiful and make use of space which would otherwise be wasted.
