A passion fruit, Passiflora caerulea probably. Not sure about the edibility, they're not the same species as those in the SMs or in passion fruit ice cream
My parents had an ornamental passion fruit which had orange fruits like those - mother said that her friend said they were edible and she (the friend) made jam from them, but that they were pretty tasteless and mother didn't recommend eating them.
Gardening in Central Norfolk on improved gritty moraine over chalk ... free-draining.
Yes I'd heard you could eat certain varieties, but haven't tried them. The one I have produced fruit similar to that and the flower was white with the purply striped centre. Have not seen the birds try them so they can't be very tasty.
I must have been lucky mine was grown on the worst soil poss it grew so strong i had to saw it down to paint the fence and the fruit was beautiful the kids used to pick them on there way to school,BUT i don't know what sort it was ,i was told it was a Passionflorer Edulis but don't quote me on that but mine was very edible exactly like the one in the pic,
I have these too. When I asked someone about them I was told only to eat them once they were orange and ripe. If you break one open they are mostly hollow inside with a small bundle of seeds covered in a fruity coating - a bit like pomegranites. I tasted some but it wasn't very exciting and I don't like that seedy crunchy kind of texture much so I have left the rest on the plant. They look better than they taste
I suggest you cut one open and try a nibble as it is a passion fruit but difficult to say which one. It will not harm you, the edible one is much more difficult to grow well outside in this country but there are a lot of the decorative ones around. I have tried tasting the decorative one which is dry and tasteless. They usually crop well after a good hot summer. The edible one usually only fruits successfully grown under glass.
All of them seem to grow profusely and need regular cutting back.

Hi pottamus, I think it is a passion flower and the fruit a passion fruit
But I would not advise eating it

Thanks for all your comments - I think I'll advise my daughter not to eat, just to enjoy them in the garden!
