The label reads passiflora incarnata. It's something I got from another gardener 2 years ago. I can't vouch for the veracity of the name, but it's growing well.
Please let me have your address so I can mail your cuttings. I use prepaid Priority Mail boxes to ensure the plants get to their destination as quickly as possible and at a reasonable cost. You can use whichever means you deem fit to ship yours; I'm definitely not fussy.
I have to defer to your observation that this may indeed be P. foetida. I was driving around 2 years ago when I noticed this passionflower that had completely overtaken both sides of a fence. A guy was tending his plants outside. I stopped the car and walked over to see the vines. He was very friendly and handed me a broken pot with 4 rooted cuttings in it. They were healthy and obviously well established. A piece of venitian blind was stuck into the soil with p. incarnata scribble in blue crayon. He asked $5.00 for it, which I gladly paid. I never regretted the purchase. It has taken over my trellis completely. The catepillars eat it to almost nothing time and time again when they get to the leaves before I can douse the plant with a generous application of BT (or three). It always recovers quickly from the caterpillars' onslaught. And now, I'll make up another marker with p. foetida scribbled on it.
