MYSTERY PLANT

Can you help?

   

I bought this plant about two years ago. There was no label on the pot. It has a single woody branch and has buds and flowers which resemble a passionfruit. I would like to plant it somewhere suitable as it looks as though it would creep. It seems hardy and likes its all year sunny position but it looks like it might need support to creep along. 

At present, the single 'branch' is about 2m high. It is very pretty. I would also like to know how to prune it so I can foster new growth. Does it bear fruit?
