I have two different varieties of emerald cedars. One has a denser foliage with shorter needles and an overall appearance that is a brighter green. The other is a darker green with longer needles. Other than aesthetics, is one better than the other? Thanks!
There is only one variety of emerald cedar, Thuja occidentalis ‘Smaragd’ commonly referred to as Emerald Cedar or White Cedar. The differences that you describe could be due to soil conditions and or sun exposure, in addition to the possibility that the two trees are different cultivars.
