Anyone know about passion flowers?

My passion flower looks a bit floppy and some of the leaves have gone brown at the ends or the edges - is this wind scorch? We had snow here in Exeter for the first time in about ten years (at this altitude) a couple of months ago. I'll try and get a picture up here of it later today. Thanks for any suggestions

 

Yes, I agree, it's early days yet for passion-flower. They do look dead, but it's amazing how they come back again.
