I have a Leylandi hedge shielding us from the neighbours, which has grown well. However there are gaps at the bottom. Is there anything that will grow there, in the shade. I had thought maybe laurel or red robin- would be lovely to see some colour. Thanks!
How tall does it have to be? The soil under leylandii is always really crappy. I've had luck with yellow archangel, it covers the ground well. It can get out of control if you leave it but it's easy enough to just yank some out.
