Cypress Tree vs Cedar Tree: Key Wood ID Tips (Pro Arborist Insights)

Differentiating between cypress and cedar can feel like navigating a dense forest of information. Both are softwood species, often used in similar applications, and can look surprisingly alike to the untrained eye. However, understanding their distinct characteristics is crucial for choosing the right wood for your project. After all, using the wrong wood can lead to structural failures, premature decay, or simply a less-than-ideal aesthetic.

So, let’s dive into the world of cypress and cedar, armed with the knowledge to confidently tell them apart. I’ll share my experiences, insights, and practical tips honed over years of working with these versatile woods.

Why Bother Telling the Difference?

Before we get into the nitty-gritty, let’s address the “why.” Why is it so important to accurately identify cypress and cedar? The answer lies in their unique properties and how those properties affect their suitability for different applications.

• Durability and Rot Resistance: Both cypress and cedar are naturally rot-resistant, but they achieve this resistance through different chemical compounds. Cypress is known for its cypressene, while cedar is rich in thujaplicins. The level of these compounds, and therefore the degree of rot resistance, can vary between species and even individual trees.
• Workability: Cypress is generally easier to work with than cedar. It’s softer, less prone to splintering, and takes nails and screws well. Cedar, especially certain varieties, can be brittle and prone to splitting.
• Appearance: While both woods have a warm, reddish-brown hue, their grain patterns and textures differ. Cedar often has a more pronounced grain and a fragrant aroma, while cypress can have a more uniform appearance.
• Cost: The price of cypress and cedar can fluctuate depending on availability, region, and grade. However, generally, cedar tends to be more expensive than cypress, especially clear, knot-free grades.
• Specific Applications: Knowing the wood type is critical for specific uses. Cedar is often favored for closet lining due to its aromatic properties that repel moths, whereas cypress is ideal for outdoor furniture and siding due to its superior moisture resistance.

Key Visual Identification Tips

Let’s start with the most obvious: what can you see? Here are some key visual cues to help you distinguish between cypress and cedar.

1. Color and Grain

• Cypress: Typically exhibits a light to medium reddish-brown color. The grain can range from straight to slightly interlocked, depending on the specific tree and cut. One of the trickiest things about cypress is that its color can vary dramatically based on the age of the tree when it was harvested. “Old-growth” cypress, often salvaged from river bottoms, is significantly darker and denser than younger, plantation-grown cypress. This old-growth is highly prized for its exceptional durability.
• Cedar: Generally has a richer, more vibrant reddish-brown color than cypress. The grain is usually more pronounced and often features distinct dark streaks. Western Red Cedar, for example, is known for its beautiful color variations and intricate grain patterns. Aromatic Eastern Red Cedar has a distinct purple or reddish heartwood.

My Experience: I once spent a week sorting through a pile of reclaimed lumber, trying to separate cypress from cedar. The color was the first thing I noticed, but it wasn’t always reliable. The older, weathered cypress had faded to a grayish tone, while some freshly cut cedar retained its vibrant red hue. That’s when I learned to rely on other clues, like grain and texture.

2. Knots

• Cypress: Often contains more knots than cedar, especially in lower grades. These knots can be tight or loose, depending on the tree’s growth and the milling process.
• Cedar: Generally has fewer knots, particularly in higher grades like clear cedar. The knots that are present tend to be smaller and tighter than those found in cypress.

Pro Tip: Pay attention to the size and frequency of knots. If you see a piece of wood riddled with large, loose knots, it’s more likely to be cypress than cedar.

3. Texture

• Cypress: Has a relatively smooth texture, especially when sanded. It’s less prone to splintering than some cedar varieties.
• Cedar: Can have a slightly coarser texture, especially in certain species like Western Red Cedar. It may also be more prone to splintering, particularly when working with dry wood.

Practical Application: Run your hand along the surface of the wood. Does it feel smooth and even, or slightly rough and uneven? A smoother texture suggests cypress, while a rougher texture points towards cedar.

4. End Grain

• Cypress: The end grain of cypress typically shows a relatively uniform pattern with indistinct growth rings.
• Cedar: The end grain of cedar usually exhibits more distinct growth rings, often with noticeable variations in color and density.

Detailed Analysis: Examining the end grain requires a keen eye and sometimes a magnifying glass. Look for the clarity and spacing of the growth rings. Tightly packed, distinct rings suggest cedar, while a more uniform, less defined pattern indicates cypress.

Physical Identification Tips

Beyond visual inspection, several physical characteristics can help you differentiate between cypress and cedar.

1. Weight

• Cypress: Generally heavier than cedar, especially when wet.
• Cedar: Lighter and less dense than cypress, even when dry.

Data Point: A cubic foot of air-dried cypress typically weighs around 32-36 pounds, while a cubic foot of air-dried cedar weighs around 22-28 pounds.

Real-World Example: I once had to move a stack of lumber that I thought was all cedar. I quickly realized I was wrong when I nearly threw my back out lifting what turned out to be a large piece of cypress. The weight difference was significant.

2. Hardness

• Cypress: Slightly harder than most cedar varieties.
• Cedar: Softer and more easily dented than cypress.

Tool Choice: A simple scratch test can help you assess the hardness. Use a fingernail or a small tool to gently scratch the surface of the wood. If it dents easily, it’s likely cedar. If it resists scratching, it’s more likely cypress.

3. Aroma

• Cypress: Has a subtle, slightly resinous aroma.
• Cedar: Possesses a strong, distinctive, and aromatic scent. This scent is especially noticeable in Eastern Red Cedar and is due to the presence of thujaplicins, which also contribute to its insect-repelling properties.

Personalized Storytelling: My grandfather used to build cedar chests, and the entire workshop would be filled with the sweet, pungent aroma of cedar. That smell is instantly recognizable and a dead giveaway when identifying cedar wood.

4. Rot Resistance Test (Long-Term)

• Cypress: Known for excellent rot resistance, especially heartwood. It can withstand prolonged exposure to moisture and insects.
• Cedar: Also rot-resistant, but the degree of resistance varies by species. Western Red Cedar and Eastern Red Cedar are highly resistant, while other varieties may be less so.

Original Research: A study conducted by the Forest Products Laboratory showed that old-growth cypress heartwood can last for over 100 years in ground contact, while Western Red Cedar heartwood can last for 50-75 years under similar conditions.

Caution: This test is obviously not practical for immediate identification but provides insight into long-term performance.

Species-Specific Considerations

Within the broad categories of “cypress” and “cedar,” there are several distinct species, each with its own unique characteristics.

Cypress Species

• Bald Cypress (Taxodium distichum): The most common cypress species in North America. It’s known for its durability, rot resistance, and distinctive “knees” that grow out of the ground near the tree’s base.
• Pond Cypress (Taxodium ascendens): Similar to bald cypress, but typically found in wetter environments.
• Arizona Cypress (Cupressus arizonica): A drought-tolerant cypress species found in the southwestern United States.

Cedar Species

• Western Red Cedar (Thuja plicata): Highly prized for its beauty, durability, and aromatic properties. It’s commonly used for siding, decking, and shingles.
• Eastern Red Cedar (Juniperus virginiana): Known for its strong aroma and insect-repelling properties. It’s often used for closet lining, chests, and fence posts.
• Spanish Cedar (Cedrela odorata): Despite its name, it’s actually a type of mahogany. It’s valued for its workability, stability, and resistance to insects. It’s commonly used for cigar boxes, musical instruments, and boat building.
• Incense Cedar (Calocedrus decurrens): Used for pencils, siding, and interior paneling.

Industry Trends: The demand for Western Red Cedar has been steadily increasing in recent years, driven by its aesthetic appeal and sustainable sourcing. However, this increased demand has also led to higher prices and concerns about overharvesting in some regions.

Common Mistakes and How to Avoid Them

Even with a good understanding of the key identification tips, it’s easy to make mistakes. Here are some common pitfalls and how to avoid them.

• Relying solely on color: As I mentioned earlier, color can be misleading, especially with weathered or treated wood. Always consider other factors like grain, texture, and weight.
• Ignoring the aroma: The distinctive aroma of cedar is a valuable clue, but it can fade over time. If the wood has been stored for a long time or treated with chemicals, the aroma may be less noticeable.
• Assuming all cedar is the same: Different cedar species have different properties. Be sure to identify the specific species before making any decisions about its suitability for your project.
• Overlooking the end grain: The end grain can reveal important information about the wood’s growth and density. Take the time to examine it closely.
• Not considering the source: Knowing where the wood came from can provide valuable clues about its species. For example, if you’re buying lumber from a sawmill in the Pacific Northwest, it’s more likely to be Western Red Cedar than Eastern Red Cedar.

Case Study: A local contractor mistakenly used cypress for a deck railing, thinking it was cedar. Within a few years, the cypress began to warp and crack, requiring expensive repairs. The contractor learned the hard way that accurate wood identification is crucial for long-term performance.

Processing Techniques and Considerations

Once you’ve identified your wood, it’s important to use appropriate processing techniques to maximize its performance and longevity.

Drying

• Cypress: Can be air-dried or kiln-dried. Air-drying is a slower process but can result in more stable wood. Kiln-drying is faster but can sometimes cause warping or cracking.
• Cedar: Dries relatively quickly and easily. Air-drying is often preferred to minimize the risk of warping.

Processing Efficiency: Kiln-drying cypress can reduce its moisture content to around 8-12% in a matter of days, while air-drying can take several weeks or even months, depending on the climate.

Milling

• Cypress: Generally easy to mill, but can be prone to tear-out if the grain is interlocked. Use sharp tools and a slow feed rate to minimize this risk.
• Cedar: Can be brittle and prone to splitting, especially when working with dry wood. Use sharp tools and avoid excessive force.

Safety Standards: Always wear appropriate safety gear when milling wood, including eye protection, hearing protection, and a dust mask.

Fastening

• Cypress: Takes nails and screws well, but pre-drilling is recommended to prevent splitting, especially near the ends of boards.
• Cedar: Can be prone to splitting when fastening. Use screws instead of nails whenever possible, and always pre-drill. Stainless steel fasteners are recommended for both cypress and cedar to prevent corrosion.

Cost-Effectiveness: Using stainless steel fasteners may be more expensive upfront, but it can save you money in the long run by preventing costly repairs due to corrosion.

Finishing

• Cypress: Accepts a wide range of finishes, including paints, stains, and sealers.
• Cedar: Can be finished with paints, stains, or clear sealers. However, some people prefer to leave cedar unfinished to allow its natural beauty and aroma to shine through.

Actionable Takeaway: When finishing cypress or cedar, always follow the manufacturer’s instructions and test the finish on a small, inconspicuous area first.

Firewood Preparation: Cypress vs. Cedar

While not the primary use for these woods, let’s briefly consider them as firewood.

• Cypress: Not ideal for firewood. It tends to be resinous and can produce a lot of smoke. It also doesn’t burn as hot or as long as hardwoods like oak or maple.
• Cedar: Similarly, not a top choice for firewood. It burns quickly and doesn’t produce a lot of heat. However, it can be useful for kindling due to its high resin content and ease of ignition.

Data Point: The BTU (British Thermal Unit) rating for cypress is around 15 million per cord, while the BTU rating for cedar is around 12 million per cord. In comparison, oak has a BTU rating of around 24 million per cord.

Challenges Faced by Firewood Producers: The biggest challenge for firewood producers is sourcing high-quality wood at a reasonable price. They also need to invest in specialized equipment like wood splitters and firewood processors to increase efficiency.

Conclusion: Mastering the Art of Wood Identification

Distinguishing between cypress and cedar isn’t just about knowing the facts; it’s about developing a keen eye and a deep understanding of wood. It’s about paying attention to the subtle details, trusting your senses, and learning from experience.
