Thuja plicata 'Green Giant'

Green Giant Western Arborvitae

Green Giant arborvitae (Thuja ‘Green Giant’) is a vigorous evergreen hybrid with rich green foliage and a broad, upright outline. It keeps its color in winter and can gain height rapidly once established.

This is a substantial screening tree for large properties and open landscapes. Plan generous spacing and sufficient clearance from buildings and utilities; its fast early growth is followed by continued enlargement.

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