My favorite passion flower is also my first, the x belotii. I found it at Home Depot (mislabeled), and it produced tons of flowers. Although the cold hit it hard, and the original plant died, about seven plants sprung about 5 feet away, and are blooming away! All those plants grown from seeds I bought have yet to produce a bloom. A great first passion flower for those interested in a recommendation.

I have since bought a "Panda," and it has pretty blooms, but doesn't bloom like a belotii.:
