My title deeds prohibit the erection of a fence or formal hedge between my property and the house next door. I’m looking for ideas as to how I could demarcate the boundary line, possibly with plants in long troughs or pots. What plants would work well? The current space is laid to gravel, so I’d like to avoid digging this up hence thinking of potted plants. I’d like something that is relatively evergreen but could still thrive in a pot. It could be quite a wide planter as there is plenty space. I live in north Scotland, so would also need to be relatively hardy 😁
