I had wonderful luck with passion flowers, but I lived in San Diego, which is quite a bit different. ( ;
I used two long, wooden potting containers from Home Depot, approx 3' x 8" x 8" each, regular old potting soil, and I put a large 8' wooden trellis up behind them. The passion flowers were gorgeous. Then I was privy to a wonderful plethora of silver winged butterflies - hundreds of them - after that, I enjoyed the abundance of lizards that would snack on the late blooming butterfly chrysalis.
Circle of life! ( :
We had a ton of hummingbirds and bees, which probably helped.
