Escallonia (I think that's the spelling). Fairly quick growing, thickish, everygreen and with flowers. Can grow tall if desired but responds well to being hacked back. Recent minus 12 degrees did no harm to mine, even though it had been severly pruned in autumn. Remember to backfill the planting trench with well rotted horse manure if you can get it. The hedge will grow fast and thick and thank you every day! Finally it has no thorns - very important as footballs roll into it in years to come.
