Popular for its evergreen sprays of fragrant green foliage, Leylandii is probably the fastest growing hedging plant. It can grow up to 1 metre (3 feet) a year. Kept trimmed, Leylandii conifers create a wonderfully dense screen of a hedge. They can reduce noise pollution and act as an effective windbreak.
Leylandii is a hybrid, accidentally created in Wales in the 19th century. It comes from two species of cypress from different parts of North America: the Monterey and the Nootka. Leylandii are ideal for normal soil conditions, sun or partial shade, exposed inland and coastal sites.
