Subalpine Fir
Pacific Silver Fir

Subalpine Fir is pyramidal, coniferous tree often found growing naturally in areas with higher elevation. A lover of cool and moist soils, this adaptable tree bears unique and attractive cones that take on a purplish-black color and grow vertically.

Subalpine Fir is often used in naturalization projects, however, this variety will act as a beautiful specimen tree on its own. Subalpine Fir has also been used to create screens and windbreaks, but keep in mind this slow grower will take some time before reaching a height that is suitable for wind protection.

Pacific Silver Fir is a tall evergreen tree native to the Pacific Northwest. It has two-toned needles, dark green on top with silvery undersides, giving the tree a distinctive appearance. The straight trunk and dense, symmetrical crown make it a striking forest species.

Pacific Silver Fir thrives in cool, moist, high-elevation forests. It is the most shade-tolerant of the true firs and among the most shade-tolerant of all native conifers, allowing it to grow beneath the canopy of older trees. It provides cover for wildlife and food from its seeds, while also contributing to the structure and stability of mountain forest ecosystems.

The species is harvested for timber and pulp and has been used ornamentally in some plantings. Well-suited for ecological restoration, naturalization, and habitat projects where native conifers are needed. Pacific Silver Fir lives up to its Latin name, amabilis, meaning “lovely,” in recognition of its striking appearance.
