Yes, Russian Vine - It looks to me as if you've got one or at the most two years' growth there - give it another year and it'll pull that trellis down. I've seen it pull downpipes and guttering off houses. When we moved here we found remains of it under the roof tiles!!! The last owner had cut if off the house and gutters but hadn't done the tiles - that's been our job. The original roots of the Russian Vine were 12 metres away at the other end of the garden!
If you really want to propagate it just stand back and watch, it'll root everywhere a branch touches the ground.
Don't say we didn't warn you!!!
