white fir
Abies concolorAlso known as Concolor Fir, Colorado Fir, Rocky Mountain White Fir
White fir trees dominate mid- to high-elevation montane forests across western North America, recognized by their flattened, silvery-blue needles that curve upward along the twigs. Crushed needles unleash a distinctive citrus fragrance reminiscent of tangerines or grapefruit. In the high canopy, erect barrel-shaped cones mature in late summer before completely disintegrating on the branch to release winged seeds.
