White Fir (Abies concolor), also known as Colorado White Fir, is a beautiful evergreen conifer prized for its soft blue-green to silvery-green needles, symmetrical pyramidal shape, and pleasant citrus fragrance when the foliage is crushed. Native to the mountains of the western United States, White Fir is an excellent choice for landscaping, windbreaks, reforestation projects, wildlife habitat, and Christmas tree production. Its attractive appearance, adaptability, and tolerance of drought once established make it one of the most desirable fir species for both home landscapes and large-scale plantings.
