Thuja or Western Red Cedar Hedges are a great choice for a fast growing evergreen conifer hedge. Thuja is an evergreen conifer similar to green leylandii but slightly slower growing making it easier to maintain as a hedge. Thuja can kept as a formal hedge from 5 foot upwards. Thuja hedges will tolerate harder pruning than a leylandii hedge and will often regrow quite well when cut back hard into older wood. The foliage of a thuja hedge is mid – dark green and has a wonderful almost fruity aroma to it, if crushed.
