Thuja occidentalis Sunny Smaragd stands out in the Thuja range as a result of its wonderful bright yellow colour and upright, pyramid-shaped habit. This Thuja does not suffer from sunburn and can therefore be placed in a sunny or semi-shaded spot. Thuja Sunny Smaragd is also easy to grow in pots. Compared to Thuja Golden Smaragd, the colour is more warm yellow and Sunny Smaragd grows faster.
