Last year I planted a clematis outside my kitchen window. The aim was that it was to wind its way up a drainpipe. However it was only little when I planted it last year so I was able to tie it up with green twine on the first clip that holds the pipe into the wall.

However its flourishing this year and its already past that clip and even though Ive tried to tie it to the drainpipe a bit further up its got nothing to attach itself to and keeps slipping down or waving around in the wind.

Ive seen some semi circular metal trellis however that needs screwing to the wall and this house is rented so I cant do that. Can anyone recommend anything suitable to put on the pipe that would work please. Its right at the very front of my house (literally three feet from the footpath) so its got to be nice to look at too.

Thank you
