I bought this on a chance from Logee's even though I knew it would take at least four hours of sun every day. It lived at home, growing but not thriving in a window with morning sun. It came to the office, where it got a brief blast of direct southern sun. It even temporarily lived on a rooftop!
It was only after our most recent move that it got everything to make it happy - four hours of warm sun, no harsh wind, a bit of humidity. It settled right in and within two months put out these blossoms that open and die one by one, like a slow-moving string of Chinese firecrackers. We quickly realized that a healthy plant was a good sign for us as well; we were enjoying more sun along with the plant.
If you are looking for inspiration you should check out the Flickr Passiflora Pool (also click on the image above). The flowers are spectacular, short-lived but worth the wait.
The University of University of Saskatchewan extension page has a bit more on the history of passion flowers.
