Thuja - western red or white cedars - are commonly known for their use as a alternate hedge to leylandii as they form a dense hedge but at half the rate. Some varieties of thuja are more for feature conifers that are suitable for flower beds and pots. They have flattened sprays of foliage and respond well to being trimmed. They like to planted in moist well drained soil and can take shade. It is know that thuja occidentalis contains a high percentage of vitamin c if you use the needles - but we have never tried this one.
