Some plants do not grow vertically. knuthii is one of them. It splays out. So you can try and tie it up or put something that you can wrap it around or something like that.

Cut it down to the soil line each spring and they grow back and will be vertical for at least a few months. Super easy to propagate too I just stick the cuttings in the ground and they root super easy.
