It all depends which Passiflora you are growing ? The most common is P cerulea - rampant when happy but does not produce edible fruit - well, it won't kill you to eat it but it has no taste, no juice.
Very attractive flowers which tend to open in sequence.
In milder parts of the UK, P "Constance Elliot" may do well in the garden - a sunny sheltered spot.
If you want to grow for edible fruit, go for P edulis.......can be either yellow or black fruit when ripe but unlikely to get a crop in the UK unless you grow them under glass.
There are many more with fantastic flowers but you need the right conditions to grow these successfully
