The Concolor Fir is a woody and hefty Christmas tree. The needles are long and flat, and can support large heavy ornaments, much like the Fraser Fir. If the needles are cracked open, they have almost a citrusy smell. These trees are heavier than the other 3 varieties and are great with needle retention.  The Concolor is a coniferous tree in the pine family Pinaceae. This tree is native to the mountains of western North America from the southern Cascade range in Oregon, south throughout California and into the Sierra de San Pedro Mártir in northern Baja California; east through parts of southern Idaho, to Wyoming; and south throughout the Colorado Plateau and southern Rocky Mountains in Utah and Colorado, and into the isolated mountain ranges of southern Arizona, New Mexico and northern Mexico. White fir live over 300 years and naturally occur at an elevation between 900–3,400 m (2,950–11,200 ft).
