Large, pumpkin orange flowers like it's mother, Passiflora parritae, this is an easier to grow hybrid from passiflora breeder Carlos Rendon. The flowers are a huge 7.5" across! If you live in a mild climate and want to make a striking statement with the street tree out front, this is the plant to grow on it....and send me a picture! I would have the vapors if I saw something like this growing in a front yard! It will also produce edible fruit if pollinated.
Keep in mind that it will not tolerate hot weather, though, so if your temps stay in the eighties and don't cool down at night for weeks at a time, you will probably have trouble keeping it alive.
This plant is grafted onto a more heat-tolerant rootstock. I live in a mild climate, but have heard from other growers in hot areas that high mountain passiflora are much easier to grow for them when grafted. Please let me know your experience in your climate. I'm very excited about this new way to grow passiflora and would love to know how it goes!

Subgenus: Passiflora, Supersection: Tacsonia (P. parritae x P. 'Mission Dolores')
Light: Full sun, part shade. There will be less flowers in part shade. It would be good to give it afternoon shade in warmer climates.
Soil: A wide range of soil, but it must be well-drained.
Fertilizer: A slow-release, bloom-booster type fertilizer is appreciated, but beware of using a fertilizer with too much nitrogen as it may push leaves at the expense of flowers.
Hardiness: Zone 9.
