Emerald Green Arborvitae (Thuja occidentalis 'Smaragd') is a classic narrow, pyramidal evergreen shrub sold in a 2.4-gallon (9.2L) container. It produces dense, scale-like foliage in a rich emerald green color that holds its vibrant hue throughout all four seasons, including winter. The upright columnar form fills out from ground level, creating a full, lush appearance without the need for additional plantings in front.

At maturity this arborvitae reaches approximately 12 to 15 feet tall with a spread of 3 to 4 feet, making it one of the most popular choices for privacy screens, formal hedges, windbreaks, and vertical accents. It is hardy in USDA Zones 4 through 8, tolerates a range of soil types, and performs well in full sun to partial shade. Once established it can tolerate dry spells, though consistent moisture during the first growing season encourages a strong root system. It grows at a moderate to slow rate and is relatively low-maintenance, requiring pruning only to shape or remove dieback. Mulching around the root zone helps retain moisture and protect roots in exposed or colder locations.

Plant in deep, fertile, well-drained soil with consistent moisture. Fertilize before new growth begins in spring and shelter from harsh drying winds. This selection is native to North America and is also suitable for container use.
