A tall, graceful evergreen conifer native to Oregon and northern California, known for its soft, feathery blue-green foliage and narrow pyramidal form. It prefers cool, moist conditions and is prized as an ornamental specimen or screen plant.

Why grow it

Port Orford Cedar offers finer, softer foliage texture than many other columnar conifers, making it valuable where a more delicate visual effect is desired in cool-climate landscapes. Its narrow, pyramidal habit suits confined spaces better than broader screening conifers, and it tolerates partial shade while maintaining good form. Compared to other Chamaecyparis species, it prefers cooler, more consistently moist conditions typical of maritime or high-elevation sites.

Watch out for

This species performs poorly in hot, dry, or windy sites where foliage can brown or die back; site selection is critical to success. In regions outside its native range, ensure adequate summer moisture and protection from desiccating winds, particularly in continental climates. Crowded planting or poor air circulation can encourage fungal issues, so allow adequate spacing.
