Emerald Arborvitae (Thuja occidentalis 'Emerald Green') is a timeless classic that will never get old. That's because its rich emerald foliage makes a peaceful and stunning backdrop for any other shrubs or perennials you wish to use nearby. Reaching a height of 10-15', Emerald Arborvitae is often used a privacy screen or formal hedge. Plant it alone as a landscape specimen where its conical shape softens the corners of buildings, breaks up long fence lines, and makes a stately statement flanking your entryway.
