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. ... more info
Black Oak One of the main differences include its ability to thrive on poor and varied soils. It is sometimes called yellow oak, quercitron, yellowbark oak, or smoothbark oak. Black Oak trees occur naturally on poor sandy or clay hillsides. This deciduous tree has deeply furrowed bark and on mature trees is nearly black. The thick, nearly black bark is marked with deep furrows and irregularly broken ridges. This moderately growing oak tree grows on dry uplands, slopes and ridges. The wood, while hard and strong is not tough. Still, it is used in much the same ways. Historically, the inner bark was important for its tannin and as a source of yellow dye. The green leaves have a notably velvety underside. |
