Abies concolor, commonly known as the white fir, is a coniferous tree native to western North America. It typically grows in mountainous regions, reaching heights of 50 to 100 feet. The tree is characterized by its soft, flat needles that are bluish-green in color and its smooth, gray bark that becomes furrowed with age. The white fir produces cylindrical cones that are 3 to 6 inches long, which mature in the fall. This species is valued for its timber, often used in construction and furniture making, and is also popular as an ornamental tree in landscaping due to its attractive appearance and pleasant fragrance.
