Passionfruit and flower are the same thing? I have a large vine on the side of my house and it has lovely flowers, but the fruits are not worth it. The ones that have orange fruits have the most stunning flowers, but the least edible fruits (well, all passion fruits are edible, some are just not worth it). I am considering cutting it back this year, if I can manage before the first frost as it has lost a couple of branches last winter and looks a bit messy. It grows at the same speed as bind weed.... so it should cover that wall again well.
I love the fact that it flowers and bears fruit until well into November. I have a north facing garden which is 90% in the shade all day and it is doing so well. I have never fed or watered it, it actually grows in a pot and seems to be drought, flood and cold tolerant.
I have heard that the purple passion fruit plant is a bit more delicate. Maybe try and grow one inside on the windowsill over the winter, so it is a bit bigger when you plant it out? I have also noticed that even though I let all of the fruit fall to the ground, not one plant has ever appeared. It is obviously not easy to grow from seed.
