White Fir is conifer tree in the pine family (Pinaceae) that is slow-growing and long-lived. The native range is the western United States in the Sierra Nevada and southern Rocky Mountains and south to the mountains of Nevada, New Mexico and Mexico It is found in elevations of 3,000 and 11,200 feet.
White fir has a narrow dense pyramidal shape with horizontal branches and drooping lower branches. In the wild, it can grow 130 to 150 feet tall but in cultivation usually reaches 30-70 feet tall and 15- 30 feet wide. It prefers moist fertile soil with good drainage in full sun to partial shade. Avoid heavy clay and wet spots, It withstands heat and drought better than most firs.
The white fir has a good Christmas tree shape when young and good needle retention after cutting. It can be used as a specimen, for privacy and screening or for shade. It is not suited to the southeastern United States.
