I have privet hedging in my little London terrace front garden which I can't really do anything about other than trim it down and keep it under control. But I want to underplant it to make it a bit more pleasant to look at. I have a couple of vincas which seems to be doing well but what else would survive? It doesn't get masses of sunlight, as there is a 3 ft wall as well but as it's west facing, it's not totally in the dark. I will be renewing the soil as much as I can with manure etc but the hedge is pretty established so whatever I put in needs to be able to fend for itself!
Any ideas?
