What Are Succulent Fire Sticks?
Succulent Fire Sticks are a colorful succulent shrub scientifically known as Euphorbia tirucalli ‘Sticks on Fire’. They belong to the Euphorbia family and are native to parts of Africa and India.
This succulent is commonly called:
- Fire sticks plant
- Pencil cactus
- Sticks on fire
- Red pencil cactus
- Fire pencil succulent
Despite the nickname “pencil cactus,” succulent fire sticks are not true cacti. They are euphorbias, which means they produce a milky white sap that can irritate skin and eyes.
The plant grows long, thin cylindrical branches that resemble pencils. During cooler weather or periods of bright sunlight, the tips turn vibrant shades of red, orange, pink, and yellow, giving the appearance of flames.
Why Succulent Fire Sticks Are So Popular
There are several reasons they have become a favorite among succulent lovers and landscapers.
Incredible Color
Few succulents produce such intense warm colors naturally. The fiery red and orange tones make this plant stand out in any garden.
Drought Tolerance
‘Sticks on Fire‘ thrive in dry conditions and need very little water once established.
Easy Maintenance
These plants are beginner friendly because they tolerate neglect better than many other succulents.
Fast Growth
Unlike slow-growing succulents, fire sticks can grow surprisingly quickly in the right conditions.
Modern Landscape Appeal
Their sculptural appearance works beautifully in modern, desert, and Mediterranean-style landscaping.
Size and Growth
Succulent fire sticks can become much larger than most people expect.
Outdoor plants may reach:
- 4 to 8 feet tall
- 3 to 5 feet wide
In frost-free climates like California and Arizona, mature plants can eventually become massive shrubs.
Indoor plants usually stay smaller but can still grow several feet tall over time.
Best Light for Succulent Fire Sticks
Lighting is one of the most important factors when growing any succulents.
Outdoor Lighting
- Full sun
- Bright direct light
- At least 6 hours of sunlight daily
More sunlight usually means stronger red coloration.
Indoor Lighting
If grown indoors, place them:
- Near a south-facing window
- In the brightest area of your home
- Under grow lights if natural light is limited
Without enough light, the plant may turn mostly green and become leggy.
How Often to Water
One of the biggest mistakes people make with ‘Sticks on Fire‘ is overwatering.
These plants store water inside their stems and prefer dry soil.
Watering Guidelines
During spring and summer:
- Water when soil is completely dry
During fall and winter:
- Water very sparingly
Outdoor established plants:
- May survive mostly on rainfall in some climates
Signs of Overwatering
Overwatered succulent fire sticks may develop:
- Mushy stems
- Yellowing branches
- Rotting roots
- Drooping growth
Signs of Underwatering
Underwatered plants may show:
- Wrinkled stems
- Dry branches
- Slowed growth
However, succulent fire sticks tolerate underwatering much better than overwatering.
Best Soil
‘Sticks on Fire‘ need extremely well-draining soil.
A good succulent mix should contain:
- Potting soil
- Perlite
- Pumice
- Sand
- Small gravel
Avoid dense, moisture-retaining soil because it can quickly cause root rot.
Best Pots for Succulent Fire Sticks
If growing in containers, choose pots with drainage holes.
Terracotta pots work especially well because they allow soil to dry faster.
Avoid pots without drainage unless you are highly experienced with succulent care.
Temperature and Climate Needs
Succulent fire sticks prefer warm temperatures.
Ideal temperatures:
- 65°F to 85°F
They are not frost tolerant and can suffer damage below freezing temperatures.
In colder climates, many people grow ‘Sticks on Fire‘ indoors during winter.
Are Succulent Fire Sticks Toxic?
Yes. This is one of the most important things to understand about succulent fire sticks.
The milky sap inside the plant is toxic and irritating.
Sap Exposure Can Cause
- Skin irritation
- Burning sensations
- Rashes
- Eye injuries
- Severe discomfort if ingested
Keep ‘Sticks on Fire‘ away from:
- Pets
- Small children
- Eyes and mouth
Always wear gloves when pruning or propagating the plant.
If sap gets in your eyes, seek medical attention immediately.
How to Propagate Succulent Fire Sticks
These are very easy to propagate from cuttings.
Step-by-Step Propagation
- Wear gloves and eye protection
- Cut a healthy branch
- Let the cutting dry and callous for several days
- Place the cutting in dry succulent soil
- Wait several days before lightly watering
- Keep in bright indirect light until roots develop
Propagation is usually very successful when done properly.
Common Problems With Succulent Fire Sticks
Although hardy, ‘Sticks on Fire‘ can still develop problems.
Root Rot
Root rot is the most common issue and is almost always caused by overwatering.
Symptoms include:
- Black stems
- Mushy branches

Sunburn
Although they love sun, plants moved suddenly from shade into intense sunlight can burn.
Acclimate gradually when increasing sun exposure.
Pests
Occasionally succulent fire sticks may attract:
- Mealybugs
- Spider mites
- Aphids
Neem oil or insecticidal soap can help control infestations.
Why Are My Succulent Fire Sticks Turning Green?

This is usually caused by:

They pair beautifully with:

Can Succulent Fire Sticks Grow Indoors?
Yes, but indoor success depends heavily on light.

In warm climates, they may grow several feet within a few years.
