About the Concolor Fir :
The Concolor Fir tree, Abies concolor, is
also known as white fir, concolor fir, silver fir, Rocky Mountain white
fir, Colorado Fir, Lows Fir, Pacific white fir. Concolor Fir trees are
large, densely-growing, narrow trees with a dome-shaped crown growing to
50 feet or more. This evergreen conifer tree is native to the
mountainous regions of the western United States.
This rapid growing fir 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. It
is a rapid grower after it becomes established. It makes a handsome
ornamental and decorative Christmas tree.
