Subalpine Fir (Corkbark Fir)

Abies lasiocarpa

The Subalpine fir is an attractive fir native to North America. A slow-growing tree, taking 8-10 years to reach 2 metres in height. It can show green, blue-green or grey needle colours and has very thick, corky bark on the trunk. The glossy needles have a white underside, holding very well after cutting. The tree also has fairly strong branches and a beautiful fragrance.
