Vines for Pergola on a deck
Want a vine to grow up my pergola - to provide additional shade and beauty. The problem is I can't plant it in ground, because the pergola is on top of a deck. Can you think of a vine that I could plant in pots, perhaps one at each of the 4 posts - that will grow quickly and far enough to work its way across some of the top this summer? Of course, I am sure I will have to cut it down each year as it will die off in the winter correct?
