Answer: This might work out. Passionflowers in general need a minimum temperature of 50 degrees to stay in bloom year round, and you can stake it or trellis it or train it on a wire hoop.
Also, although you did not include your location in your question, I should mention that some passionflower vines are surprisingly winter hardy. Passiflora incarnata is hardy to USDA zone 6, dying back to the ground each winter.
Enjoy your new plant!
