Cupressaceae

Botanical Name

THUJA occidentalis 'Smaragd'(EMERALD)

Plant Common Name

Eastern Arborvitae, White Cedar

General Description

Eastern Arborvitae is a pyramidal, cone-breaing evergreen tree native to eastern North America. Its flattened sprays of dense, rich green foliage provide year-round interest. The selection Emerald ('Smaragd') features a compact, conical habit and bright emerald-green scaled needles that hold their color all winter, unlike many forms of the species.

Arborvitae needs full to partial sun exposures and moist, well-drained soil. Emerald is useful for screening and hedges or as a specimen or accent.
