Hi all, can anyone please suggest a plant that I could use to get some privacy from my neighbours? We have a wall which is about 4 foot tall and there is a gap between my neighbours and me, I don't really mind the fact that I can speak to my neighbour but all the cats in my area use my wall as a through route! I have placed a trellis over the gap and have started to grow some climbers, clematis and roses, however the clematis dies back during the wintertime. Is there anything that I could use that is fast growing and would cover the gap? I was contemplating some bamboo? Would appreciate any help!
