This plant comes from Brazil. It is highly prized there for its fruit: very sweet and about 3"x5" in size. That is quite large compared to regular passion fruit available in US markets. It is mostly eaten raw: seeds and all! The Portuguese name for it is "Maracuja Doce."
Apparently, it could be grown in south FL, but it needs to be hand pollinated (you'll need two vines for that). It seems that mason bees might pollinate it too. The fruit forms 70-90 days after pollination. It needs to turn yellow to be ripe for eating.
Here's a post with nice pictures of the fruit in comparison with other varieties of passion fruit.

The vine can withstand mild frost (to 28F) for short periods and will defoliate, but it grows back.
The seeds are fairly hard to germinate, but it also can be propagated by hard-wood cuttings and air-layering.
Both flowers and fruit are highly fragrant, so it's no surprise that another common name for it is "Fragrant Granadilla."
