Introducing the Pencil Cactus, botanically known as Euphorbia tirucalli ‘Fire Sticks’ (also called Sticks on Fire), a striking succulent prized for its sea coral-like appearance and vibrant, loosely branching pencil-thin stems that develop brilliant shades of green, orange, and red.

Native to Southern Africa, this unique succulent belongs to the Euphorbiaceae (spurge) family, not the cactus family (Cactaceae), though it is commonly referred to as “Pencil Cactus” because of its cactus-like form and upright growth habit. It is also known by several other common names, including fire sticks plant, sticks on fire succulent, fire plant, red pencil tree, milk bush, and Euphorbia tirucalli ‘Rosea’.


When exposed to direct sunlight, the tips turn red, which is why they are also called firesticks.

This fast growing evergreen succulent can grow up to 30 feet tall and 10 feet wide, forming a thicket of brilliantly colored vertical stems with loose branches.

The unusual stems of this firestick plant, which are as thin as pencils, have a reddish-golden hue that becomes yellow in the summer and red again in the winter.

The pencil cactus flowers boast vibrant yellow, pink, or orange blooms in the summer and spring, making them a true showstopper in any garden.

The pencil cactus is extremely drought tolerant and hard to kill, and as a result, is a great, low-maintenance, easy-care plant for your home or garden.

You can grow your pencil cactus indoors year-round as a houseplant. If planting outdoors, it's best to do so in the spring when temperatures are warm and stable. This cactus grows faster than many other cacti, making it a striking addition to your garden or home.

If you cut your pencil cactus, be careful—the thick, white sap is toxic and can cause skin irritation, burns, or severe eye irritation if it gets into your eyes. While highly irritating, some cultures have historically used it in traditional medicine for treating growths like warts and tumors, though it is not safe for home remedies. Always wear gloves when handling the plant and wash your hands thoroughly if you come into contact with the sap.

When and How to Water Your Pencil Cactus 

This pencil cactus firestick plant can withstand droughts and doesn't need to be watered frequently to survive. Watering these perennial succulents should be done every 3–4 weeks or when the soil feels dry. Let the soil completely dry out between waterings, and if in doubt, give your fire plant a little more time before watering again.  Less water is needed for humid locations and indoor spaces. Pay attention to how the pencil cactus looks and adjust the watering accordingly.

Remember that succulents in the desert can go for weeks or even months without water, so water them sparingly during their rest phase and moderately during their active growing season.

Pro Tip

Most people like to see the red tips that give this Euphorbia tirucalli its firestick name. Note that it is stress that causes the tips to go red. So, the art is to stress the firestick plant a bit, but not too much. So, give it a lot of light and water it less than other succulents, so it is thirsty but not dying of thirst.

Overwatering can also cause the Euphorbia tirucalli 'Firesticks' tips to turn red, but it can also lead to root rot and other problems. So, if your pencil cactus is not turning red in full sun, it's possible that it's not experiencing enough stress to produce the anthocyanin pigments or that it's receiving too much water.

Light Requirements - Where to Place Your Pencil Cactus 

Like most succulents, indoors, the Euphorbia tirucalli firesticks need bright, indirect sunlight to thrive, so choose the brightest area in the house.

Potted indoor pencil cacti require four hours of direct sunlight, which can be achieved by locating them on a sunny south or west-facing windowsill. 

If you are growing these firestick succulents outdoors, make sure that they receive at least six hours of direct sunlight per day.

Partial shade may be tolerated as long as your pencil cactus gets the majority of the sunlight that it needs when it's planted outside. This succulent plant won't thrive if left in the shade for a long time. Its colors become more vibrant the more sunlight it receives.

In order to avoid sunburn, it is preferable to acclimatize your pencil cactus first before moving it outdoors or increasing the amount of sunlight it receives.

Optimal Soil & Fertilizer Needs 

The firestick Euphorbia is a succulent plant that likes very airy, porous, nutrient-rich soil with a pH of 5.5–6.5. Succulents require fast-draining soil that dries completely between waterings. Ideally, you want to use our specialized potting mixGo to soil cactus mix blend 1 gal 4 qt cacti succulent dirt compost growing media that contains 5 natural substrates and organic mycorrhizae to promote the development of a strong root system that helps your Euphorbia firesticks Pencil Cactus to thrive. 

When it comes to fertilizing your pencil cactus plant, it only needs a small amount of fertilizer applied once a year in spring. Cacti prefer a fertilizer with lower doses of NPK, with a maximum ratio of 5-10-5 that is higher in phosphorus than nitrogen.

Hardiness Zones & More 

When growing indoors as a houseplant, the Euphorbia firestick can tolerate temperatures between 65 °F and 75 °F. Your Euphorbia firestick plant performs well in temperatures above 30 °F. However, it can withstand temperatures below that, but only for short periods of time.

In the United States, the Euphorbia tirucalli is mostly an indoor plant, but if you live in southern Florida or Hawaii then you can cultivate it outdoors in USDA zones 10 -11.

Growing these pencil cacti in containers is the best option if you live in an area with harsh winters.

By doing this, you can bring your Pencil Cactus indoors during the winter or any time there's a chance of frost or snow. Normal house humidity is fine for this Euphorbia, but it prefers dry conditions. 

Wildlife - Euphorbia tirucalli Attracts the Following Friendly Pollinators

The Euphorbia tirucalli flowers attract a variety of pollinators, such as bees, butterflies, and hummingbirds, with their bright colors and sweet nectar. These pollinators play a crucial role in the ecosystem by helping to fertilize plants and promote biodiversity.

According to ASPCA, the Euphorbia tirucalli 'Firesticks' is mildly toxic to humans and pets. It can irritate the skin, eyes, and gastrointestinal tract. However, it is safe to touch as long as precautions are taken to avoid contact with the sap. Wear gloves when handling this plant to prevent any potential skin irritation.

How to Propagate Your Pencil Cactus

When it comes to pencil cactus propagation, one common method is through stem cuttings. Simply take a cutting from a healthy pencil cactus, let it dry for a few days, and then place it in well-draining soil. Another method is through division, where you carefully separate the offsets or side shoots from the main plant and plant them individually.

Key Takeaways

  1. The stems of firesticks are as thin as pencils (hence the name) and turn a fire-red in the winter.
  2. Euphorbia Firesticks is a stunning variety that changes color with the seasons, turning bright red or orange tips in cooler temperatures or full sun.
  3. This succulent has a rapid growth rate, reaching up to 30 feet tall when grown outdoors, with a branching, upright form.
  4. During the spring and summer, the yellow flowers bloom in clusters on the end of the branch, usually for just a few days.

The Bottom Line

Overall, the pencil cactus (Euphorbia Firesticks) is a unique and striking succulent plant that adds a touch of elegance to any space. With its slender, pencil-like stems and vibrant green color, this sticks-on-fire cactus can truly be a showstopper. However, it's important to remember that the pencil cactus is not a true cactus but rather a succulent. It requires minimal care, preferring bright light and well-draining soil. By providing proper pencil cactus care, you'll have a beautiful and unique Euphorbia firestick plant that will thrive for years to come.

Simple Magnesium Powder That Is Easy Enough to Take
I just started taking this Magnesium Citrate powder, so it is too early to know if it will help with things like muscle support, heart health, bone health. Magnesium is an important mineral for the body and it plays a role in muscle function, nerve signaling, and overall balance, so I like the idea of adding it to my routine. The citrus berry flavor is not too horrible, which is a pleasant surprise because some magnesium powders can taste pretty rough. This one is easy enough to drink without feeling like you have to force it down. I also like that it is third party certified and comes with a full sixty servings. I will need more time to see if it makes a noticeable difference, but so far the experience has been simple and the taste is manageable.

2 months supply, tasty berry bubblegum flavor, no morning cramps.
I've been taking Magnesium supplements for a long time, usually in capsule form. Starting from about age 45 I kept getting these awful morning calf cramps. Especially stretching, or on cold morning. The sudden agony was unexpected and concerning. Magnesium is the answer and this water-soluble magnesium from Thorne is no exception. For this particular problem, calf cramps. The results are noticable within a couple of days. If I stop taking magnesium for 3-5 days the cramps come back. Thorne powder has a berry flavor that is very similar to bubble gum. It dissolves easily without leaving any lumps. Is great to help you take your other supplements. I've been taking this for about 3 weeks with no cramps. Price is a little higher than capsules typically are. This works for me and the tub should last two-months if you follow the directions.

Easy Way to Add Magnesium Support
Magnesium is one of those supplements many people find helpful as part of their wellness routine. The powder format makes it easy to adjust serving sizes and mix into drinks. One thing I liked was the citrus berry flavor, which made it more pleasant than many unflavored supplements. Overall, a convenient magnesium option from a well-known brand

Great Taste and Mixes in Water Well
I’ve been using this magnesium citrate powder for a little while now, and overall it’s been a positive experience. One of the standout aspects is how well it mixes. It dissolves easily in water with minimal residue, which makes it much more convenient compared to some other powdered supplements I’ve tried. The citrus berry flavor is also quite good: light, slightly sweet, and easy to drink without being overpowering. The powder format makes it simple to adjust how you take it (more or less water, etc.), and I didn’t notice any strong aftertaste. From a general usability standpoint, this checks the boxes I look for in a supplement: good taste, easy mixing, and consistent quality. Thorne also has a strong reputation, and this product feels in line with that in terms of formulation and overall experience. As with any supplement, individual experiences can vary, but from a taste, mixability, and convenience perspective, this has worked well for me. Overall, this is a solid option if you’re looking for a magnesium citrate powder that’s easy to take on a regular basis.

Great Magnesium Blend That Actually Works
Size: 100 Count (Pack of 1), Size: 100 Count (Pack of 1)
I’ve been taking Life Extension Magnesium Caps (500 mg) for a few weeks now, and I can really feel the difference. It’s a blend of magnesium oxide, citrate, and succinate, and I’ve noticed improved sleep quality and fewer muscle cramps at night. The capsules are easy to swallow and don’t upset my stomach, which has been an issue with other magnesium supplements I’ve tried. Plus, I like that they’re vegetarian-friendly and come in a 100-count bottle, which lasts a good while. What I appreciate most is how balanced this formula feels. I take it mainly for sleep, muscle support, and overall well-being, and I genuinely notice I feel more relaxed, especially in the evenings. For the price and quality, it’s a great value. I’ll definitely keep this one in my daily routine.
