Thuja occidentalis 'Smaragd'

Emerald Green Arborvitae

For dense evergreen hedge that holds its rich colors and sturdy form throughout the seasons, the Emerald green arborvitae is an excellent choice. A highly adaptable Thuja, it also thrives in the hotter and more humid climates of the U.S. South, making it a consistently popular hedge in that region.

There are a number of immediate benefits to choosing the Emerald green arborvitae for your next hedge:

  • Keeps its deep emerald color through the winter
  • Tolerates dry spells once it is established
  • An especially great shrub for taller hedges or screens
  • Ideal for small yards and other tight areas
  • With a narrow pyramidal habit, the Emerald green arborvitae has a great natural shape and also responds well to regular pruning.

The tree’s disease resistance and general resilience make it a popular low-maintenance hedge.

The Emerald green arborvitae performs well in a variety of soil and weather conditions, including snow and ice. Even the coldest of winters, the tree maintains its shape and color.

Its rich foliage and attractive narrow form make the tree an excellent choice to plant in a row for a formal screen.

This arborvitae prefers loamy, well-drained soil with consistent moisture.

The common name of arborvitae, or “tree of life”, comes from the early settlers in North America who learned from Native Americans that the tree’s foliage, sap, bark and twigs had medicinal properties.
