What Is a Pencil Cactus?
Euphorbia tirucalli or Indian Tree Spurge is a succulent, spineless tree or tree with a hefty trunk and brown primary branches and pencil-like, green new branches.
The leaves cluster near the top of the branches. They also have small flowers that appear in bracts and the tips of branches change brightly colored after being planted in bright light.
It is semi-tropical to tropical by nature and it is reliably winter-hardy all the way to USDA Zone 11.
It is now thriving in the southern areas of Florida and California in Zone 10.
It’s drought-resistant, and, when planted outside in warmer climates it can grow to the height of 30 feet. It is usually used to create a hedge or a barrier.
If it is grown in warmer conditions, it is reduced in size and used as an indoor plant.
About the pencil cactus
- The pencil cactus (or Euphorbia tirucalli), unlike its aquatic relative, enjoys bright light conditions and meals of frequent water rather than one large watering session. This makes it the perfect addition to your office, bedroom, or living space. They have striking foliage, blooms, and other features but are not hard to care for as long as they have enough light and water.
- Pencil cacti aren’t quite as hardy as other succulents, but they won’t need overwatering nearly as often either. They store a large amount of water in their fleshy branches, enough for a long time.
- Euphorbia Tirucalli bushes benefit from soil that is slightly sandy that is well-drained. The bushes are susceptible to root decay therefore it is best to let the soil dry before you overwater.
- In order to ensure that your plants grow equally It is recommended to change the Euphorbia Tirucalli plants frequently. They’re slow-growing and require transplants every 2 to 3 years.
- Another important aspect that should be taken into consideration when choosing a Pencil Cactus planting pot is the material in which it is made. Although you can plant your pencil cactus in an unglazed container, it will be the ideal option for you if it is an unglazed container that has excess drainage.
- The pencil cactus is a species of hydrophilic plant characterized by its physical properties and appearance. It produces latex which can be an excellent alternative to fuel. The sap of the pencil cactus is considered poisonous. It is very irritating and can cause blindness so it is important that you handle it with care.
- The sap of this plant is what makes it so dangerous. If eaten directly from the plant, it can cause serious reactions in dogs, cats, and humans alike (it’s recommended to wear protective glasses and gloves while handling them). In fact, it’s been known to kill small animals such as dogs, who have been attracted by the smell of its fruit or flowers.
What are the characteristics of a pencil cactus?
Pencil Cactus is cultivated as a big houseplant that can grow to ceiling height if it is placed in a large container. They typically have a narrow, upright shape with branches that begin to shrink as they increase in size.
- While these species were claimed to be beneficial in combating cancer before, recent research suggests that they prevent cancerous cells from developing by suppressing your immune system.
- They are shrubs or tiny trees that can reach as tall as 9 meters when in the natural environment. When the environment is right they can grow upwards of 1.8m high when they are planted in the container.
- Euphorbia Tirucalli Plants are also called “milk bush” because they release toxic, milky, white latex sap out of their stems.
- Pencil cacti feature slender, succulent, green branches 7mm in thickness, that alter color throughout the cooler months, changing to either pink, orange or yellow. That’s why they’re often referred to as “Burning Sticks”.
- They are great planted alongside Sedum Angelina and Sedum Firestorm species since they showcase their vibrant colors. In addition, they can be paired with succulents and cacti due to their similar environmental needs.
- In rare instances, they can produce small yellow flowers at the end of the stems. They are quite tiny and are only noticed if you pay attention enough, which is why they usually are not noticed.

Is pencil cactus sap toxic?
Here’s the bad news. One of the most common terms for this Euphorbia is Milkbush which is a well-deserved name. Like other plants in the Euphorbia family, milk bush creates the well-known white latex when cutting the stem however, none of them produce the amount of sap these succulents produce. The poisonous components present in the sap are believed to be diterpene esters.
My troubles started when I went to the greenhouse to collect some cuttings of this intriguing plant for an upcoming sale of plants. I was able to find sap all over my hands, and around one eye.
Signs associated with an allergic reaction appeared within an hour after exposure. It started with a burning in the eye. The issue quickly spread to another eye, and finally, my lips began to numb around two hours after I had experienced the affliction. Around this time I had the most severe bout of fidgeting that I have ever experienced. The breath loss began within four hours. A quick trip in the hospital emergency department and an injection of an antihistamine, the recovery was nearly immediate.
My experience was one of the classic cases of anaphylactic shock. This is the same type of condition people who are allergic to peanuts dairy products, or soy products suffer from.
It is a fact that plant poisonings can occur however the rate of fatalities is so small that it’s not any different in terms of statistically comparing it to being struck by the impact of a meteor. However, a significant proportion of the 2.3 million instances of exposure to humans that were reported to the nation’s system of Poison Control Centers in 2000 were related to plants.
Most of them were toddlers who took an ingesting from the plant, and then an anxious parent ran to nearby hospitals. Although some ornamental plants can be poisonous, the probability of a child inhaling enough of them to trigger negative reactions is very low.
My own experience has highlighted the difficulty in constructing an entirely complete and widely accepted list of plants that are poisonous. Many would not think of peanuts as poisonous. For the vast most people the pencil Cactus poses no risk however, I consider it a danger and treat it with a good amount of respect. The plants all make a mix made of organic substances.
For children who are young, it is always best to keep plants away from reach and to instruct their children from the earliest age to only put food items in their mouths.
This is the best soil for pencil cactus because it comes in a large bag and is also fairly inexpensive. With its porous texture, Hoffman 10404 can hold ample amounts of water for your pencil cactus and other plants. It allows for good drainage which helps prevent over-watering, in turn extending the life spans of your plants. This soil can be easily mixed with potting soil if you want to add necessary nutrients, although it already contains some fertilizer that has been tested safe for cacti and succulents.
