Description
Thuja occidentalis 'Smaragd' shrub 30-40 cm C2 | Emerald green arborvitae
Thuja 'Smaragd' shrub is an evergreen form of Thuja occidentalis 'Smaragd', also known as Emerald Green arborvitae. This product is supplied as a shrub, not as a standard tree. Its compact, upright and narrowly conical habit gives it a clear, close-knit outline in the garden. The green foliage usually remains green through winter, so the shrub keeps its colour when many other plants have lost their leaves. It can reach a mature height of about 4 metres; no mature width is specified. The name 'Smaragd' identifies the cultivar, while the shrub form describes the plant offered here. This distinction matters when choosing a plant for a particular garden use: the upright, narrow-conical outline is the feature to consider, rather than a standard tree shape. The flowers are inconspicuous and yellow-green, and the product data also describes the plant as fruit-bearing without giving further details. Thuja 'Smaragd' may suit a hedge, a specimen position or group planting. Its evergreen foliage and defined shape make it useful where a steady green presence is wanted in the garden.
