The Concolor Fir (White Fir) tree lives over 100 years and naturally occurs at an elevation between 2,950-11,200 ft. It is native to the mountains slopes of the western United States including the Cascade, Sierra, and Rocky Mountains. This tree is best grown in rich, medium moisture, slightly acidic, sandy/gravelly, well-drained soils in full sun to partial shade. (Best in full sun.) Established trees tolerate some soil dryness, but best performance usually comes with moist soils. The Concolor produces lightly barrel-shaped cones (to 3-6” long) that are most often yellowish-green, maturing to brown or purple. As is distinctive with the firs, the cones appear upright on the branches. This tree may not produce cones and seeds for up to the first 40 years. Its bark is ash-gray and smooth, but will furrow with age. The word Concolor means "all one color" and thus, you can expect a beautiful bluish green color year round with this tree.
This is a popular tree for use as ornamental landscaping and as a Christmas tree. This is a durable tree for the Colorado Front Range and has no serious insect or disease problems. This tree does not do well with urban pollution—so it's not recommended along busy streets or in areas with poor air quality. This tree grows in an elegant pyramidal shape with a symmetrical outline. The height and width can vary depending on soil and site, with mature height ranging between 40-60 feet tall and 20-30 feet wide.
