In North America, western hemlock (Tsuga heterophylla) is the most common species of hemlock. It is a large evergreen tree that can grow to be over 200 feet tall. The needles of the western hemlock are short (less than 1 inch long) and have a blunt tip.

They are arranged spirally on the twigs and are dark green in color with a white stripe on the underside. The cones of the western hemlock are small (about 1 inch long) and oval-shaped. They hang down from the branches and have scales that are thin and papery.

  • Look for a coniferous tree with needles that are flat, slightly curved, and 2-5 cm long
  • Examine the bark of the tree; it should be thin and have a reddish-brown color with vertical ridges
  • Check for cones that are small (1-2 cm long), oval-shaped, and reddish-brown in color
  • If the tree meets these criteria, it is likely a Western Hemlock

What is the Difference between Eastern And Western Hemlock?

There are a few key differences between eastern and western hemlock trees. For one, eastern hemlocks are generally taller, reaching up to 80 feet tall compared to the 60-foot height of western hemlocks. Additionally, eastern hemlocks have smaller leaves, measuring just 1-2 inches long as opposed to the 2-4 inch leaves of their western counterparts.

Finally, the bark of an eastern hemlock is smooth while the bark of a western hemlock is more rough and scaly. Eastern and western hemlocks are both evergreen coniferous trees that are members of the pine family. They are found in North America, with the majority of eastern hemlocks growing in the Appalachian Mountains and the northern Midwest, while most western hemlocks are located in the Pacific Northwest.

Both types of tree prefer cool, moist climates and can live for hundreds of years. Hemlocks are valuable timber trees and are used in a variety of industries including construction, furniture-making, paper production, and even as fuel for wood-burning stoves. The wood is strong yet lightweight, rot-resistant, and takes well to stain or paint finishes.

Hemlock tree sap can also be used to produce an essential oil with a number of medicinal applications.

What Does Western Hemlock Wood Look Like?

Western hemlock wood is a light to medium brown with a reddish tinge. The sapwood is creamy white and the heartwood is pinkish brown. It has a straight grain, with a fine texture and moderate natural luster.

How Can You Tell If Wood is Hemlock?

Hemlock wood is a softwood that is commonly used in the construction of furniture and cabinets. It has a light brown or red color with a straight grain pattern. Hemlock is easy to work with and takes stain well, making it a popular choice for many woodworkers.

There are several ways to tell if wood is hemlock. One way is to look at the color of the wood. Hemlock typically has a light brown or reddish hue.

Another way to identify hemlock is by its grain pattern. The grain of hemlock wood is straight and consistent, making it easy to identify. Finally, hemlock is a softwood, so it is relatively easy to carve or sand down.

Is the Western Hemlock Poisonous?

No, the western hemlock is not poisonous. The western hemlock is a species of coniferous tree in the family Pinaceae. It is native to North America, occurring in the west from southeastern Alaska to central California and inland to northwestern Montana.

Is Western Hemlock Tree Poisonous

No, western hemlock trees are not poisonous. These coniferous evergreens are native to the Pacific Northwest region of North America and can grow up to 230 feet tall. The needles and cones of these trees are used in a variety of ways, including as a food source for some animals and as an ingredient in some traditional medicines.

Western Hemlock Adaptations

The western hemlock is an evergreen tree that is native to the Pacific Northwest region of North America. It is the largest member of the genus Tsuga and can grow to be over 200 feet tall. The bark is reddish-brown and scaly, and the leaves are dark green and needle-like.

The cones are small, brown, and papery. The western hemlock is adapted to its environment in a number of ways. The thick bark provides protection from fire and insects, while the dense foliage helps to shade the ground and retain moisture.

The needles are coated with wax, which helps to prevent water loss in dry or windy conditions. The roots are shallow but strong, anchoring the tree in place on steep slopes. The western hemlock plays an important role in the ecology of its forest ecosystem.

It provides habitat for many animals, including birds, squirrels, and bears. Its fallen needles create a nutrient-rich soil that supports other plants in the forest floor. And its large size makes it an important source of wood for humans who use it for lumber, paper products, and more.

Western Hemlock Vs Douglas Fir

There are many different types of trees in the Pacific Northwest, but two of the most common are western hemlock and Douglas fir. Both of these trees have their own unique features, and they each have their own benefits and drawbacks. Here is a comparison of western hemlock vs Douglas fir to help you decide which tree is right for you.

Size: Western hemlock can grow up to 200 feet tall, while Douglas fir typically only reaches 100-120 feet in height. Shape: Western hemlock has a conical shape with dense branches, while Douglas fir has a more open pyramid shape with fewer branches. Leaves: Western hemlock has small, needle-like leaves that are dark green on top and white on the underside.

Douglas fir has larger, flat needles that are dark green on both sides. Bark: Western hemlock bark is thin and smooth, while Douglas fir bark is thick and rough. Wood: Western hemlock wood is light and soft, making it easy to work with but not very strong.

Douglas fir wood is heavier and harder, making it more difficult to work with but much stronger in terms of weight bearing capacity.

Western Hemlock Height

The Western Hemlock is a tall evergreen tree that can grow up to 115 feet in height. It has a straight trunk with reddish-brown bark and rounded, dark green needles. The Western Hemlock is native to the Pacific Northwest region of North America and is the state tree of Washington.

It grows best in moist, shady areas and can be found in forests, along streams, and in other wet habitats.

Hemlock Tree Identification

Hemlock trees are one of the most common coniferous trees in North America. They are easily identified by their needle-like leaves and conical shape. Hemlocks can grow to be very large, with some specimens reaching over 200 feet tall!

These majestic trees are an important part of many forest ecosystems, providing shelter and food for a variety of wildlife. Unfortunately, hemlocks are under threat from a non-native insect called the hemlock woolly adelgid. This tiny pest sucks the sap from hemlock needles, causing them to turn yellow and eventually die.

If you think you’ve spotted a hemlock tree, there are a few things you can look for to be sure. First, check the needles. Hemlock needles are attached singly to the twig and are about ½ – 1 inch long.

They are dark green on top and have two white bands on the underside. The cones of a hemlock tree are small (about ¾ inch long) and brownish-purple in color. If you find a tree that matches these descriptions, congratulations!

You’ve found a hemlock! These beautiful trees play an important role in our natural world and deserve our protection.


If you’re out for a hike in the Pacific Northwest, you may come across a tree that looks like a cross between a fir and a pine. This is the western hemlock, Tsuga heterophylla. Here’s how to identify it.

The western hemlock can grow to be over 200 feet tall, with a trunk up to six feet in diameter. The bark is thin and scaly, ranging in color from reddish-brown to gray. The needles are short (about an inch long), flat, and arranged spirally around the twigs.

They are dark green on top and have two white stripes on the underside. The cones are small (about an inch long), oval-shaped, and hang down from the branches. If you see a tree that matches this description, it’s likely a western hemlock.

But there are some other trees that it could be confused with, so here are some helpful tips for telling them apart: The western hemlock grows in moist areas along the coast of British Columbia, Washington, Oregon, and northern California. If you’re not sure if you’re in one of those areas, look for nearby streams or rivers – the western hemlock likes to grow near water sources.

Another tree that it might be confused with is the mountain hemlock (Tsuga mertensiana). These two species often grow together and can look quite similar at first glance. However, the mountain hemlock has longer needles (up to two inches) and its cones are more round than oval-shaped. Protection Status
