Smaragd' is derived from the Greek word for Emerald which gives away this conifers most distinguishing feature - it's alluring shade of vibrant green foliage.
As well as its distinct foliage, Thuja 'Smaragd' is perhaps one of the neatest cone shaped conifers, growing slowly to form a slender column to 1.8m or more high but only 90cm across at the base. The flattened sprays of foliage give the plant a crushed velvet appearance that will enhance the garden throughout the year. An excellent focal point as a specimen or grows well as a hedge or in groups in a larger border. This hardy conifer is very effective in a pot placed either side of a door, or planted in a border where it will add an architectural punctuation to a planting scheme. If a more formal appearance is desired Thuja 'Smaragd' can be trimmed lightly to shape.
Lustrous foliage and an attractive shape makes this versatile conifer an excellent feature plant for a border, pot or hedge.

Thuja 'Smaragd' prefers good light levels and a sunny position and so it is best grown in a South, East or West facing aspect which offer good levels of sunlight.
This conifer would look great in a rockery or gravel garden, planted formally framing doorways or in avenues, or planted in groups in a mixed border for architectural impact. Preferring a well drained soil and tolerant of most soil conditions, Thuja 'Smaragd' is also suitable for growing in pots and containers when a loam based compost should be used.
When positioning, aim to shelter from drying winds and avoid spots that are very exposed. In the first season water well and feed occasionally but once established the tree should grow well without further care. No pruning is needed although trimming can be done to create a neater more formal shape if required.
