Abies concolor ssp. lowiana, also known as the Sierra white fir and Low's fir, is a subspecies of white fir native to the western United States. It is found in the mountains of California, Nevada, and Utah, at elevations of 3,000 to 10,000 feet. The Sierra white fir is a large tree, growing to heights of 100 to 150 feet. It has a narrow, conical crown and blue-green needles that are 1 to 2 inches long. The cones are 3 to 5 inches long and hang down from the branches.
The Sierra white fir is a valuable timber tree. The wood is strong and lightweight, and is used for a variety of purposes, including construction, furniture, and pulpwood. The tree is also popular for landscaping, and is often planted in parks and gardens. The tree is named after Hugh Low, an English nurseryman. The Sierra white fir is a long-lived tree, with some individuals living for over 500 years. The tree is a host plant for the Sierra Nevada bristlecone moth. It is also a keystone species in the Sierra Nevada ecosystem.
