I am looking for hedging plants that are suitable for a south facing front garden in London with limited space and which grow well in narrow planters and don't require much maintenance. Have been looking at Photinia, Choisya and Geonia Laurel, and wondered if there were any other suggestions. I don't really need it to be a hedging screen (although it will border a road) and just looking for something that I can easily manage. Thanks in advance!
