Traditionally, the most well-known and recognizable types of Christmas trees are evergreen fir or pine trees.
In ancient times, before various types of Christmas trees were identified and popularized, families hung evergreen boughs across their doorsteps and windows.
The modern Christmas tree tradition began in Germany during the 16th century when the first decorated trees were put up inside homes during the Christmas season and the tradition was continued when made popular by Queen Victoria.1
18 Types of Christmas Trees: Ranked Worst to Best
If you’re learning about how to cut your own Christmas tree, you should understand that not all Christmas trees are created equal, and some varieties are preferred over others because of the benefits they provide, while a handful of varieties are avoided because their disadvantages outweigh the benefits.
Below is a complete list of 18 types of Christmas trees: ranked worst to best:
Worst Christmas Tree: Norway Spruce
This type of Christmas tree ranks worst because they droop quickly and are shade-intolerant. If the lower branches of the tree receive too much shade, the shape of the tree can become uneven.
Worst Needle Shedding: Norway Spruce
The Norway spruce also has the distinction of being the fastest needle shedder of the popular Christmas trees. This tree is not recommended for lengthy indoor use.25
Worst For Allergies: Pine Tree
Pine trees may be covered in residual pollen which could cause an immune system overreaction when breathed in. In addition to this, artificial Christmas trees that have been stored away and are covered in dust can also cause an allergic reaction in asthma and allergy sufferers.
Pesticides used on certain varieties of Christmas trees are harmful to the environment. Some Christmas tree farms ship trees to different states, which leads to increased carbon emissions.26
Worst For Environment:
Live Christmas Trees vs Artificial Christmas Trees
The manufacturing of artificial Christmas trees releases extra carbon emissions, especially because most of these trees are produced in China and shipped worldwide. Discarded trees become harmful plastic waste filling up landfills9
Worst For Bugs: Norwegian Pine
Norwegian pine trees are well known to be covered in bugs most of the time, and this type of live Christmas tree should be shaken thoroughly before being taken indoors.
Worst For Affordability: White (Concolor) Fir
White Fir Christmas trees generally take a long time to grow, which can make them more expensive.
Worst For Heavy Ornaments: Balsam Fir
Balsam Fir trees have very flexible branches, which means they cannot hold heavy ornaments.
Worst For Scent: Blue Spruce
One of the biggest reasons live Christmas trees are so popular is because of the fresh, woodsy scent they produce. The Blue Spruce doesn’t have much of a fragrance, and when the needles are broken, it releases an unpleasant scent.
Worst For Color: Scotch Pine
The Scotch Pine is among the worst of the options when it comes to choosing a vibrant-looking Christmas tree, because of its dull coloring.
Best Christmas Tree: Balsam Fir
Even though the Balsam Fir is not great for heavy ornaments, it is the best all-around Christmas tree with a classic shape and dark green color. The tree emits a strong scent, and it has great needle retention.
Best For Needle Retention: Scotch Pine
When a Scotch Pine tree is properly watered, it won’t lose its needles for a long time. Proper watering will ensure that the Scotch Pine retains its needles for up to four weeks.
Best For Least Bugs: All Except Norwegian Pine
Most of the time, live Christmas trees are not covered in bugs, which means that most can be brought inside without any trouble, except for the above-mentioned Norwegian Pine, which should be shaken out first.
Best For Allergy And Asthma Sufferers:
Fir Trees, Leyland Cypress, and Eastern White Pine
Pine pollen is a major allergy trigger, which makes firs, spruces, and cypresses a better option.
Best For Environment:
Locally Grown Live Christmas Tree
Any locally grown live Christmas tree is the best choice for the environment, as it cuts down on the carbon emissions associated with shipping. Most real Christmas trees are grown on Christmas tree farms – the numbers totaling 350 million – which means that forests are left mostly unscathed over the holidays.10
Best For Affordability: Real Christmas Trees
Real Christmas trees are still cheaper than their artificial counterparts – with real trees retailing between $80 and $95, while artificial trees can cost as much as $325.
Best For Heavy Ornaments: White Spruce
The White Spruce has short, stiff needles which make the tree an excellent choice for ornaments of different shapes, sizes, and weights.
Best For Scent: White Fir
The White Fir releases a citrus fragrance when its needles are crushed.
Best For Color: Colorado Blue Spruce
The Colorado Blue Spruce has a silvery color, making it a perfect choice for a wintry Christmas holiday.11

Real Christmas Tree Options
A real Christmas tree27 can be found in every US state, as well as Canada. In the US alone, around 30 million real Christmas trees are sold every year.
The states that produce the most real Christmas trees are Oregon, North Carolina, Michigan, Pennsylvania, Wisconsin, and Washington.12
Whenever a single real Christmas tree is harvested, up to 3 seedlings are planted during the next planting season. Throughout Northern America, there are at least 4,000 Christmas tree recycling programs.
Because it takes a long time for trees to mature, recycling efforts are commendable and can be considered a tree planting carbon offset. If you are one of those people who are uncomfortable cutting these trees and want to do more to mitigate these actions, you can seek assistance from carbon offset providers but before doing so, make sure to take the ecological footprint quiz as it’s the first step in achieving this goal.
Best Type of Christmas Tree
The Douglas Fir is one of the most popular options in the US, because of its pyramid shape and full growth.
However, the Balsam Fir is the best overall choice for the best type of Christmas tree when it comes to scent and color, as well as needle retention.

Douglas Fir Christmas Tree
The Douglas Fir Christmas tree29 species was first reported by Scottish botanist, David Douglas. The Douglas Fir is not a true fir, which is why its name is often written as Douglas-fir.
Douglas Firs grow in central California, western Oregon, Washington, and Alaska and can reach heights of 76 meters.
These trees have been used as Christmas trees since the 1920s, and aside from their popularity during the holiday season, they provide valuable timber for Europe, New Zealand, and Chile.

The Balsam Fir Christmas tree was first described in 1768. These popular Christmas trees prefer moist soil, and cooler temperatures and are typically found in Canada and southern Pennsylvania.
In addition to being used as a Christmas tree, the Balsam Fir’s resin is used to produce glue and cold remedies.14
