Thuja occidentalis 'Smaragard

Emerald Green Arborvitae

Emerald arborvitae (Thuja occidentalis ‘Smaragd’) grows into a narrow, regular spire with glossy green foliage. Its close branching and dependable winter color give the garden a clear evergreen outline throughout the year.

The slim form works well in orderly rows, beside an entrance, or among broader shrubs. Even a narrow tree needs adequate root space and separation from walls and paths as it develops.

Plant in full sun with moist, well-drained soil. Water consistently during establishment and allow enough room for the natural outline to develop.
