I guess it's too late to ask that question. In spite of all the advice to the contrary, in April 2008, we planted a couple wisteria vines against the fence that surrounds our pool (on the farthest end from where all the pump and plumbing lines run). For a few years I had been longing for a wisteria vine but was afraid to take that leap for fear it would become this destructive plant encompassing our property and perhaps, one day, us! Finally, I decided that it was a gamble that I was willing to take. I can't say for sure how I will feel about these vines ten years from now; but I can say that this spring - it was worth it!
