I have a trellis right outside of my sliding glass door leading off the porch. I want to plant something in the spring that will actually use it. Here is what I was hoping for - a flowing vine that will bloom almost all summer or atleast quite a bit and I would really like one that will come back every year. OR - I would like to grow something functionable on it. Some kind of vining fruit/ veggie. Of course it would be nice if it came back every year but I will not push my luck. It is a very sunny location with well drained soil. Any suggestions?
