It's a Leyland cypress hedge, which is evergreen. I'm not sure I'd recommend it as it needs cutting twice a year (unless you want a 20 foot hedge which the neighbours might object to) and takes a lot of moisture from the soil. It's a miracle anything grows near it - there is actually a gap between the shrubs and the hedge, and also my clients take a lot of care in their garden and probably feed and water their plants. Yew (taxus baccata) is also evergreen and not quite so fast-growing.
