Pacific Silver Fir

Pacific silver fir is a cool-climate conifer of the Cascades and coastal ranges, reaching 50 to 80 feet in its narrow, pyramidal form. The needles, pressed forward along the twig, gleam silvery-green beneath, giving the tree its common name. You see this species rarely in Puget Sound lowland gardens; it thrives in the mist belt of higher elevations where fog and moisture provide the cool, humid conditions its name (amabilis, meaning lovely) suggests it demands.

Silver fir requires partial shade and adaptable soils in the acidic pH range (3.3 to 6.0). In the Puget Sound region, it struggles with summer dryness and heat; succeed only at higher elevations with consistent moisture and cool air. Root diseases, needle blights, and the balsam woolly adelgid pose management challenges. This is an excellent tree for mountain properties and coastal areas within its range, but a poor choice for warm, dry lowland sites.
