I’m about hr drive from Melbourne in 2bedroom unit in lifestyle village with small back yard where climbing plants were already planted against north facing back fence on wire trellis when I moved in.  2plants are star jasmine and quite small in height.  App on my phone today said the other 3plants are potato vine … I’ve never heard of these before.

In approx 2.5 months these 3 vines have outgrown the height of the fence and constantly producing new stems which, unsuccessfully, I’ve been trying to thread through the wire trellis as far down toward the ground as I can.  

anyone have any knowledge about these plants?  Is it ok if I chop the vine back to same height as the star jasmine which is just below my knee height.  With plans to have cat enclosure installed in few months not far from one vine, am I best to get rid of that plant completely?
