Western Red Cedar

Western Red Cedar (Thuja plicata)

Western Red Cedar (Thuja plicata) is a towering, long-lived evergreen conifer prized for its aromatic foliage, reddish bark, and exceptional durability. Also known as Western Arborvitae, this native species provides shade, structure, and reliable year-round screening for large landscapes while offering valuable timber and habitat benefits.

Distinctive Features

This majestic tree can reach 50 to 70 feet tall and 15 to 25 feet wide in cultivation, forming a narrow pyramidal crown that broadens with age. Its soft, flattened sprays of glossy green foliage release a pleasant cedar scent when crushed, while the fibrous reddish-brown bark peels in vertical strips. Mature trees develop graceful, layered branching that gives them a strong architectural presence in the landscape.
