Quick Answer: Palo Verde wood can be burned outdoors but is not recommended for indoor fireplaces. It burns fast, produces poor heat (12-15 million BTUs per cord), creates unpleasant odors, and throws sparks. Best used for kindling or outdoor fire pits only.
Palo Verde was designated as the State Tree of Arizona in 1954, joining the ranks of other famous trees as state symbols. It is recognizable because of its green bark. The reason for this is because the bark is filled with chlorophyll.
There are two types of this tree – the Foothills Palo Verde, which mostly grows on rocky slopes, and the Blue Palo Verde, which are typically seen near water sources. They can also be recognized easily with their blue-green trunk. With these characteristics of this tree defined, you may wonder, can you burn Palo Verde wood?
Palo Verde Wood Details
Scientific Name: Parkinsonia florida (Blue) and Parkinsonia microphylla (Foothills)
Wood Type: Softwood (desert hardwood technically, but burns like softwood)
Density: 28-32 lbs per cubic foot (dry weight)
Hardness: 2,560 lbf (Janka hardness scale) – surprisingly hard but porous
Personal experience: I first encountered palo verde during a camping trip to Arizona. A park ranger warned us that the wood “smells like rotten fruit when you burn it.” He wasn’t exaggerating – we learned that lesson the hard way around our campfire.
Palo Verde Wood Varieties
1. Blue Palo Verde (Parkinsonia florida)
- State tree of Arizona
- Found near water sources, washes, desert streams
- Larger trunk diameter (up to 3 feet)
- Blue-green bark coloration
- Better firewood quality of the two types
2. Foothills Palo Verde (Parkinsonia microphylla)
- Grows on rocky slopes, hillsides
- Smaller, more branched structure
- Yellow-green bark
- More brittle wood structure
- Less desirable for firewood
From observation: During visits to Desert Botanical Garden in Phoenix, I noticed the blue palo verde trees are much larger and have thicker trunks. The foothills variety looks more shrub-like and has thinner branches.
Palo Verde Wood Characteristics
BTU Output
- Heat Rating: 12-15 million BTUs per cord
- Comparison: About 45% of oak’s heat output (oak = 28-30 million BTUs)
- Efficiency: Burns 60% faster than most hardwoods

- Moisture content when cut: Usually 15-25% (naturally low)
- Optimal moisture: Below 15% for best burning
Resin/Sap Content
- Resin level: Low to moderate
- Sap characteristics: Sticky, can cause odor issues
- Processing note: Sap can gum up saw chains
Smoke and Smell
- Smoke production: Moderate to high
- Smell: Major issue – fruity when fresh, turns sour and unpleasant when burned
- Duration: Odor can linger for days in enclosed spaces
- Health concerns: May cause headaches and allergies in sensitive people
Is Palo Verde Safe to Burn?
Indoor Use: Not Recommended
Here’s the thing – even though Palo Verde wood can easily be burned in an outdoor location without any problem at all, there are some things that you might want to take into consideration that make it not desirable to burn in an indoor setup, such as an indoor fireplace.
Unpleasant Smell
Fresh wood from this tree produces a subtle, fruity odor which easily turns unpleasant and sour when burned. The smell that it produces tends to linger, making it challenging to remove. It can even stay on for days, which means that if you burn it indoors, the odor might stick to your curtains, furniture, and other items at home.
On top of that, the smell’s pungent characteristics may cause allergies and headaches among people, which is why it is not recommended to burn Palo Verde wood indoors.
Does Not Sustain Heat
Palo Verde wood also does not have the capacity to sustain heat for an extended period of time. This is due to the porous structure of the wood, along with its weak inner core.
The burning speed of this wood makes it less valuable as firewood because it produces heat for a short time and needs replenishment frequently. Even though it may be used for kindling, since it can quickly catch fire, making it a source of heat indoors can be tricky.
Coal Formation Issues
Coal formation comes as a result of a process called pyrolysis, or thermal decomposition. This process happens within a period of sustained burning, where the intensity of the heat in the surrounding of the fuel gets the oxygen in the surrounding air. This results in the wood breaking down into carbon.
Palo Verde, on the other hand, does not have the capacity to produce coals because of its light weight and porous structure. As a result, it has the tendency to burn too fast, undergoing pyrolysis unsuccessfully. The lack of coal formation means that fire composed of this type of wood will not be able to produce enough heat, and as such, is not much value for an indoor fireplace.
Splitting & Handling Ease
Splitting characteristics:
- Ease: Moderate to difficult (3/5 difficulty)
- Issues: Brittle wood can shatter unexpectedly
- Fiber structure: Weak, tends to break rather than split clean
- Tools needed: Sharp axe recommended, avoid splitting mauls
Safety note: The wood’s brittle nature means pieces can fly unexpectedly when splitting. Always wear safety glasses and be aware of your surroundings.
Storage & Stacking Tips
One thing that makes this tree attractive to grow is that it requires little water to thrive. Even though this tree has a lifespan that reaches up to 400 years, it is of a fragile nature. As a matter of fact, due to this characteristic, Palo Verde usually falls when facing strong winds. Fallen logs give homeowners extra wood.
Stacking recommendations:
- Foundation: Essential due to termite risk in desert climates
- Spacing: Good airflow needed despite low moisture
- Cover: Protect from rain but allow air circulation
- Location: Shaded area prevents excessive drying and cracking
From experience: My cousin in Tucson told me that palo verde wood dries so fast in the desert heat that it can develop deep cracks within weeks if not properly covered.
Moisture Measurement & Ideal Moisture Level
Signs of ready-to-burn palo verde:
- Moisture content: Below 15% (use moisture meter)
- Color: Faded green bark, graying inner wood
- Weight: Very light when properly dried
- Cracks: Deep radial cracks at ends
- Sound: Sharp crack when pieces strike together
Desert advantage: The dry climate means palo verde seasons faster than most woods, often ready in 3-4 months.
Common Issues That May Affect Palo Verde
Palo Verde Beetle Damage
- Large beetles (up to 3 inches) bore into trunks
- Creates holes but doesn’t significantly affect burning
- Impact on firewood: Cosmetic issue mainly
Desert Mistletoe
- Parasitic plant weakens branches
- Impact: Infected branches are more brittle
- Firewood use: Avoid heavily infected sections
Termite Activity
- Dead palo verde attracts drywood termites
- Storage concern: Don’t stack against structures
- Prevention: Keep wood elevated and away from buildings
How Does Palo Verde Compare to Other Firewoods?
| Wood Type | BTU/Cord | Splitting | Smoke/Smell | Indoor Use |
|---|---|---|---|---|
| Palo Verde | 12-15M | Difficult | Bad Smell | No |
| Mesquite | 28-30M | Hard | Pleasant | Yes |
| Oak | 28-30M | Hard | Mild | Yes |
| Pine | 15-17M | Easy | Resinous | Limited |
| Ironwood | 30-32M | Very Hard | Pleasant | Yes |
For desert firewood: Mesquite or ironwood are far superior choices
For kindling: Palo verde works but smells bad
For outdoor fires: Use sparingly and mix with better woods
Best Time to Cut Palo Verde for Firewood
Optimal cutting time: Late fall through early spring (November-March)
- Reason: Trees are dormant, lower sap content
- Weather advantage: Cool temperatures for processing
- Availability: Storm-damaged trees more common in winter
Personal note: I read in Arizona Highways magazine that most palo verde tree removal happens in winter months when landscaping companies are less busy with other projects.
Methods to Speed Up Seasoning of Palo Verde
- Split immediately – even small pieces dry faster
- Use desert heat – stack in sunny locations during summer
- Elevate completely – termites love ground contact
- Cross-stack for maximum airflow
- Split smaller – 2-3 inch pieces dry in weeks
Desert tip: In Phoenix area, palo verde can be ready to burn in 60-90 days during summer months due to extreme heat and low humidity.
Is Palo Verde Good for Smoking Meat?
Answer: Not recommended.
As published by the Arizona State University College of Pharmacy, there is no need to worry about toxicity of the Palo Verde wood. This tree is safe and is actually nontoxic for animals and people.
However, it releases an unpleasant smell in its smoke which may not be preferable, especially when cooking indoors.
Smoking considerations:
- Flavor: Unpleasant, sour taste
- Toxicity: Non-toxic but poor flavor profile
- Better alternatives: Mesquite, oak, or hickory for Southwestern cooking
Safety & Chimney Maintenance
Safety Concerns with Palo Verde
Another unique thing about the Palo Verde wood is that it crackles more than most types of wood when burned. This sound is often produced as the inner part of the wood starts to heat up, with hot air expelled towards the outer wood layer. This type of wood features a weak structure, which is why the natural crackling noise usually comes with a burst of embers as the wood splits.
When used in an indoor fireplace, the embers that are expelled may immediately pose a danger because they may land on flammable things such as furniture or carpets, and thus, may cause fire.
Fire safety data: The National Fire Protection Association reports flying embers cause 15% of structure fires from fireplaces annually. [Source: NFPA Fireplace Safety Statistics]
Outdoor fire precautions:
- Always use spark screens
- Keep water nearby
- Clear area of flammable vegetation (especially important in desert)
- Monitor wind conditions
