Yesterday we paid a visit to one of the nurseries we frequent on a regular basis and off to one side we spotted the sorry-looking, tangled plant in the photo. All the owner could tell us about it was that it had arrived in a delivery from one of his suppliers, that on arrival it had a few small pink flowers and the supplier told him it was an 'Italian jasmine'. The only reference I can find to Italian jasmine is Jasminum humile and they have yellow flowers. If it is a jasmine the only one that came to mind was Jasminum beesianum. Maybe forumers can suggest other possibilities.
Anyway, he asked us to take it home to see if we could resuscitate it and possibly in the fullness of time positively identify it. Will report any progress if it occurs.
