Abies concolor, also known as the white fir or Rocky Mountain white fir, is a large evergreen tree native to the western United States and Mexico. It can grow up to 130 feet tall and has a narrow, conical shape with a straight trunk and dense branches.
The needles of Abies concolor are typically blue-green in color and can grow up to 3 inches long. The cones are cylindrical in shape, typically 4-6 inches long, and have a purplish tint when young, maturing to a brownish color.
White fir is a popular ornamental tree and is often grown for use in landscaping and Christmas tree production. It is also used for lumber, pulpwood, and fuelwood.
Abies concolor grows best in cool, moist climates and is commonly found in mountainous regions, from 4,500 to 9,000 feet in elevation. It is a relatively slow-growing tree, with a lifespan of up to 350 years.
The white fir is an important species for wildlife, providing food and habitat for a variety of animals, including birds, squirrels, and deer. It is also used by Native American tribes for medicinal purposes and in cultural practices.
