True firs are all through the genus Abies and there are between 40 and 55 species of those evergreen conifers worldwide. They’re members of the pine household (Pinaceae) and could also be distinguished from fully totally different pines by their needlelike leaves. Pines have their needles linked to the division in clusters of two, three, or 5, whereas firs and spruces have them linked individually to branches.
Fir timber are discovered all by means of a great deal of North and Central America, Europe, Asia, and North Africa, rising in elevated elevations and mountains over many of the ranges.
Noble, Fraser, Douglas, and balsam firs are terribly stylish Christmas timber, usually thought of the proper timber for this purpose. A number of these are furthermore desired ornamental yard timber.
Firs have totally no insect or decay resistance when uncovered to the pores and pores and skin surroundings. Because of this fact, their wooden (typically known as North American timber, SPF [spruce, pine, fir]or whitewood all through the timber commerce) is generally truly helpful for cheaper structural developing and furnishings. Left exterior, the wooden would not usually final bigger than 12 to 18 months, relying on the type of native local weather it is in.
Figuring out North American Firs

Fir needles are typically transient and principally cozy with blunt concepts. The cones are cylindrical and upright. The kind of a fir tree is slender with inflexible, upright, or horizontal branching versus the “drooping” branches attribute of some spruce timber.
Not like these on spruce timber, fir needles are fats and flat (suppose “FFF”). You would not be succesful to roll a fir needle spherical in your fingertip, whereas a spruce needle has 4 sides so chances are high you will roll it. Fir needles are pretty cozy, nonetheless spruce needles are sharp.
Fir needles are linked to twigs, typically in two rows. The needles develop outward and curve up from the twig, forming a flattish spray. There is a distinct lack of needles on the underside sides of the twigs, not like spruces that carry needles in a whirl all by way of the twig. In true firs, the underside of every needle is linked to a twig by one issue that looks as if a suction cup. That attachment differs from that of spruce needles, which be part of with a peg-like petiole (the small woody projection makes a spruce’s bark relatively rather a lot rougher than a fir’s).
Fir tree cones are considerably fully fully totally different all by way of species. People not usually see true fir cones up shut due to they develop within the route of the very best of the tree. These cones are formed like an elongated oval and disintegrate on the limb (seldom dropping to the underside intact), they usually perch upright and usually ooze resin.
Balsam Fir (Abies balsamea)

The cold-loving balsam fir is North America’s northernmost fir. Though it has an in depth fluctuate in Canada, it grows primarily all through the northeastern United States. Its needles are flat with two white bands on the underside (they’re linked spirally to the branches, nonetheless twist spherical to kind two rows on one aircraft). You will see little disks the place the needles be part of the division.
The balsam fir is small to medium in dimension, with a conical kind, and prefers moist—even swampy—boreal forest environments. You will arrange it by its most distinguishing function: a slender and pointed, spire-like crown. These timber are shallow-rooted and usually get blown over in windy situations.
Pacific Silver Fir

Whereas the bark of assorted firs is characteristically furrowed, that of a mature Pacific silver fir, native to the Pacific Coast and Cascade Vary of the Northwest, is distinctly grey and scaly, rising in peculiar plates. Juvenile timber exhibit smoother bark nonetheless with resin blisters all by way of. As a shade-tolerant tree, it is usually discovered all through the understory beneath relatively rather a lot bigger hemlocks.
The needles are equivalent to those of the grand fir—darkish inexperienced on extreme with white strains on the undersides. Nonetheless the needles stage ahead and upward, moderately than mendacity flat as grand fir needles do. The cones of the Pacific silver fir sit upright and alter from inexperienced to purple. As quickly as they disintegrate, they depart a cone core spike on the branches.
California Purple Fir (Abies magnifica)

Discovered all through the mountains of Oregon, Nevada, and California—considerably all through the Sierra Nevada fluctuate—the California pink fir is treasured for its lumber, used extensively for framing and plywood. Moreover it’s grown commercially as a Christmas tree. When left to mature, these timber can attain spectacular heights of 200 ft (even 250 ft in uncommon circumstances), with a diameter of 6.5 ft.
The bark of youthful California pink fir timber is grey and clear, with resin blisters. Because of the tree ages, the bark roughens and develops fissures, taking over an additional orange-red coloration. The blue-green needles are four-sided, not flat. Needles furthermore curve equivalent to the ends of a hockey stick the place they join with their branches. They’re linked spirally to the division, nonetheless curve spherical to be above it.
Cones are yellow-green when youthful and brown when mature, and launch seeds to the wind all through the autumn.
Noble Fir

The noble fir shares its northwest fluctuate with the Pacific silver fir. So, how does one inform the 2 aside? For starters, the noble fir grows relatively rather a lot taller, as rather a lot as 300 ft. Truly, irrespective of dwarf varieties being normally used as Christmas timber, the noble fir is the tallest and all-around largest member of the true firs (its botanical title, “procera,” really means “tall”). Naturally, its cones are relatively rather a lot higher than these of the Pacific silver fir.
As with fully totally different firs, chances are high you will arrange a noble fir by its needles. They’re going to be blue-green, with white bands on all sides, and organized in a spiral on the shoots. A noble’s needles are formed like hockey sticks and curve away from the division as if they have been combed ahead.
Grand Fir (Abies grandis)

Like noble firs, grand firs are notably enormous, rising as rather a lot as 200 ft. The 2, nonetheless, differ of their needles. Not identical to the noble fir’s hockey stick-like needles, grand firs have flat needles with rounded and notched ends. They’re darkish inexperienced with white bands beneath and a groove on the very best. “Needles are organized to kind flat sprays that present each the higher and cut back surfaces of the twig.”
The bark on youthful grand fir timber is evident and lined in resin blisters and white spots, turning into additional furrowed over time.
Each noble and grand firs are thought of subalpine, nonetheless the grand fir is hardier to elevations beneath 5,000 ft. It grows all through the Cascades and the northern portion of the U.S. Rocky Mountains.
White Fir (Abies concolor)

The white fir could be the one true fir to find out ensuing from its flat, bluish-to-silvery-green needles that stretch from all sides of the division and curve outwards and upwards. The needles measure between 1.5 to some inches in measurement. Cones can develop to six inches and are olive inexperienced when youthful, turning purple after which brown with maturity. They stand upright on the branches and disintegrate lastly.
This pyramid-shaped tree has a broad rising fluctuate that stretches from the Cascades to mountainous areas of northern Mexico. It could be present in California, Utah, Colorado, Arizona, and New Mexico, too. Exterior its native fluctuate, the tree is generally grown for decorative options and located on Christmas tree farms.
Fraser Fir (Abies fraseri)

The Fraser fir is uncommon in its pure Appalachian fluctuate nonetheless extensively planted and grown for Christmas timber. It is fastidiously associated to the balsam fir, one totally different frequent Christmas tree selection, each acknowledged for his or her cozy needles and good perfume.
A singular attribute of the Fraser fir is that its branches angle barely upwards, giving it a compact look. Its needles are normally darkish inexperienced and happen in two rows. They’re flattened with a groove on the higher facet and two white bands on the underside, the place the pores (stomata) are situated. Needles are 1/2 to 1 inch extended, darker inexperienced on the very best, and lighter on the underside.
The Fraser fir produces cones with a “bract” that extends earlier the scales, giving the cones the appears to be of drooping on the division. That is a really highly effective distinction from the balsam firs, which haven’t acquired these seen cone bracts.
Fraser fir can attain a most peak of 80 ft and a diameter of 1 to 1.5 ft. Youthful timber have smoother grey bark with resin blisters; with age, the bark develops skinny, papery scales.
Douglas Fir (Pseudotsuga menziesii)

Though positively one in every of many important well-known varieties, the Douglas or Doug fir will not be an precise fir “due to the cones grasp down off the division and fall off full.” It belongs to the genus Pseudotsuga and is native solely to western North American forests. It may presumably develop to an infinite 300 ft in peak, second solely to redwoods.
Due to they maintain intact, Douglas fir cones can usually be discovered (in copious components) in and beneath the tree. This distinctive cone has a three-pointed bract (snake tongue) between every scale. Together with this, the Doug fir is simple to find out by its needles, which whirl all through the division like these of a spruce nonetheless are notably softer. In addition to they taper on the attachment stage to the division, not like fully totally different fir needles.
The needles stand proud of all by way of the division, resembling a bottle brush; nonetheless the needle concepts are cozy in contrast with spruce’s sharp parts. Some youthful specimens rising all through the understory must have flat needles, all through which case you’ll arrange the tree by looking for the enduring buds which can be pointed, papery, and reddish-brown.
