Could you please tell me if there are any thorny plants that grow in dark places? I have some annoying children that live in house behind mine (so our gardens back onto each other) and they are always climbing or sitting on the fence. It is dark and not much sunlight gets to it so I'm assuming roses are out of the question? Many thanks.
You can try looking at barberry shrubs. Raspberry or blackberry bushes will serve as well, but with little light they will not produce fruit. But they will grow in shade.
