White firs are
large, densely-growing, narrow trees with a dome-shaped crown
growing to 50 feet or more. Native to the mountainous regions of
the western United States, this tree is the most
drought-resistant of all native firs. Although it can exist on
poor, dry sites, the white fir grows most vigorously in moist,
well-drained, acid soils in protected locations. An important
horticultural plant in the eastern states, it is commonly
planted in Canada because of its attractive foliage, moderately
fast growth, hardiness, and drought and shade
tolerance.
