The grand fir tree is a medium to large fir tree found in North America. It was first described by a Scottish botanist, David Douglas, who has also lent his name to the Douglas fir. Its main adaptation is the fact that it can grow in various kinds of soils.
Fir
Fir is any of the species of conifers belonging to the genus Abies included in the Pinaceae (or pine) family. These large trees, although closely related to cedars, can be distinguished from other conifers by their soft cones that perch upright like candles. Unlike the paired needles of spruce and bunched, cluster-like needles of pine trees, fir needles attach singly to the twigs with the arrangement resembling a small suction cup. Several fir species, including the balsam fir, are used as ornamental trees.

List of Different Types of Fir Trees
The genus Abies includes 48-56 species of true firs that are classified into nine extant sections and one extinct section. Other coniferous trees such as Douglas fir, joint fir, and hemlock fir are also called firs, but they are not true firs because they belong to different genera like Pseudotsuga, Ephedra, and Tsuga. The various sections of fir trees along with the species are given below:

In addition to the abovementioned fir species, there are several cultivars, including ‘Glauca’, ‘Revoluta’, ‘Nana Compacta’, ‘Pendula’, ‘Loggerhead’, ‘Little Jon’, and ‘Stairii’.

Interesting Facts
- Parts of the Himalayan fir can be used for producing incense. Its needles are used for producing essential oil that helps in treating rheumatism.
- The grand fir is considered one of the tallest and fastest-growing fir species.
- Since the Fraser fir is similar to the balsam fir in appearance, it is referred to as ‘she-balsam’.

Subalpine Fir
The Subalpine fir tree is the most widely distributed fir species in North America after the balsam fir. It is also the smallest of the true firs inhabiting the western United States.
Nordmann Fir
The Nordmann fir, named after the Finnish zoologist Alexander von Nordmann, is a large coniferous tree found in certain Caucasian countries. Scientists have observed two distinct subspecies of the tree – the Caucasian fir and the Turkish fir, with their range of distribution culminating in Northern Turkey at about 36°E longitude.
Balsam Fir
Balsam fir is a species of small to medium-sized North American coniferous trees with a dense, symmetrical pyramidal crown. Known for its spicy fragrance and dark green color, the balsam fir has been commonly used as a Christmas tree over the years.
Korean Fir
The Korean fir tree is a small to mid-sized evergreen conifer, found in the mountains of South Korea. It is a beautiful plant with ornamental foliage, revered across the world as a decorative tree for gardens and landscapes.
Fraser Fir
Fraser fir is a coniferous tree found in the southern Appalachians in southeastern America at high altitudes between 3,900 ft to 6,683 ft. This fir species, noted for having a strong turpentine scent, exhibit a well-proportioned appearance with good needle retention ability. It has a conical crown consisting of straight twigs that are sometimes angled slightly upwards. The branches of the young trees are more compact and dense compared to those of the matured Fraser firs.
Noble Fir
Noble fir, known for its beautiful symmetrical appearance, is a tall conifer species found in the Pacific coastal ranges of North America at an altitude of 910-1,680 m (3,000-5,500 ft). It has long and pointy leaves that turn upward, revealing the branches below. When young, the tree has smooth, gray bark with resin blisters; but at maturity, it becomes reddish-brown, with a rough, fissured texture.
Concolor Fir (White Fir)
The concolor fir is a species of coniferous trees found in the western parts of North America at an altitude of 3,000-11,200 ft (900-3,400 m). Its small, needle-like leaves occurring in rows are usually flat and are without stalks. The leaves at the apex are curvier and thicker than the leaves below.
The young trees have smooth, gray, thin barks with conspicuous resin-bearing pockets. However, as they grow old, the trunks become thick, light gray or reddish-brown in color, and have deep furrows with flattened ridges.
