Thuja occidentalis 'Nigra'

Thuja occidentalis ‘Nigra’, commonly known as ‘Nigra’ American arborvitae, is an evergreen conifer with a narrow, dense, pyramidal habit, particularly appreciated for its intense dark green foliage that maintains its color well in winter. Darker and more vigorous than the ‘Smaragd’ type, it quickly forms a compact and uniform hedge, ideal for privacy screens and linear plantings. Its dense, scaly foliage offers excellent pruning capabilities while maintaining a consistent texture. Thuja occidentalis ‘Nigra’ prefers full sun to partial shade and well-drained, slightly moist soil. Very hardy and adaptable, it tolerates northern climates and provides a reliable and structural solution for residential landscapes requiring a durable evergreen hedge.
