Euphorbia Lophogona Care And Propagation Guide

Euphorbia lophogona is a captivating succulent that is also dubbed “White Crown of Thorns” and originates from Madagascar. This striking plant belongs to the Euphorbiaceae family, thriving in subtropical or tropical dry forests. 

Unfortunately, its existence is jeopardized by habitat loss. Despite these challenges, it has gained popularity as a resilient houseplant, celebrated for its ability to adapt and thrive in various environments.

In this article, I will cover essential tips for cultivating this unique succulent, from creating optimal growing conditions to propagation techniques and common issues.

Key Takeaways

  • Euphorbia lophogona is a beautiful succulent plant from Madagascar with bright green leaves and unique flowers.
  • It can grow in different sunlight conditions and temperatures between 53 to almost 90 degrees Fahrenheit.
  • The plant needs regular watering but be careful not to overwater it, as this can cause root rot.
  • Propagation is easily done through cuttings from the mother plant, which should then be planted into sandy soil specifically for succulents.
  • For happy growth, use low nitrogen fertilizer and repot every 2-3 years in a larger pot with holes at the bottom.
  • Protection from frosty weather is important along with handling care because of its irritating milky sap.

Euphorbia Lophogona Overview

Euphorbia lophogona, often referred to as the “White Crown of Thorns,” stands out as a unique succulent plant due to its unusual morphological features. Originating in Madagascar’s subtropical or tropical coastal rainforests, it is part of the large Euphorbia family.

It has a particular resilience, thriving in temperatures spanning from 53°F (12°C) to nearly 90°F (32°C). Beyond being visually appealing with its vibrant blooms and rich foliage, Euphorbia Lophogona also plays an important role as a natural air purifier, absorbing numerous airborne pollutants common within homes.

Its versatile nature makes it an eye-catching addition for plant lovers and those seeking greener indoor environments alike.

Appearance & Size

This succulent boasts glossy bright green and elliptic leaves that differ from typical succulents. This shrub presents unbranched or sparsely branched stems which come alive during the blooming season with striking yellowish-green flowers encircled by pink to white petals.

Each leaf can grow up to 2.5 cm long, providing vibrant contrast against its unbranched or sparsely branched stems.

Euphorbia Lophogona Care Guide

Understanding the ideal conditions for growing Euphorbia lophogona is key to its successful cultivation, from perfect sunlight and temperature to watering needs and soil preference.

It requires caution when handling this plant due to its poisonous milky sap that causes skin irritation and potentially severe eye damage if not dealt with immediately. I recommend always using gloves when planting or repotting to prevent any accidental contact with this harmful substance.

Ideal Sunlight and Temperature

Crown of Thorns has a wide adaptability to sunlight. While it prefers partial sunlight exposure, it can flexibly adjust to varying light levels in its environment.

Optimum growing temperatures for this succulent range from 53°F – 57°F (12°C – 14°C) in cooler weather to 82°F – 89°F (28°C – 32°C) during warmer periods. Be mindful that these euphorbia plants should not be exposed to frost conditions as they could undermine their health and overall growth.

Despite its resilience and flexibility with light conditions, providing suitable temperature ranges is crucial for robust development.

Watering Requirements

This succulent needs consistent watering, but it is crucial to let the soil dry out between each watering. This prevents overwatering, a common issue that can cause root rot and damage your plant.

It’s paramount to select a container that features adequate drainage holes. Overwatering becomes less likely when excess water has an escape route, preventing root decay and promoting healthier growth.

Bigger pots offer more room for growth but remember, not too large that it hampers proper air circulation around the plant.

During propagation stages, the soil should stay slightly moist until roots are well-established. 

Soil Requirements

Euphorbia lophogona prospers best in well-draining soil with good moisture retention. A blend of sandy soil and compost works well as it ensures swift water drainage, safeguarding the roots against rot.

Including manure can enhance the nutrient content of your mix.

Fertilizing Requirements

Fertilizing your Euphorbia lophogona requires a specific approach. A low nitrogen, high phosphorus, and potassium fertilizer is ideal for this unique plant. The fertilization process usually takes place during the spring, summer, and mid-autumn seasons.

Regular application will boost the overall health of your succulent and can even stimulate flower production. It’s always best to choose a formula that is specifically designed for succulents’ nourishment needs to truly allow them to thrive.


Repotting your Euphorbia lophogona is a critical step in maintaining its health. This process should be done every 2-3 years, preferably during the spring or early summer months.

Selecting a larger pot enhances root growth and ensures the longevity of your succulent houseplant. Remember to choose a container with adequate drainage holes to avoid waterlogging and potential root rot issues.

Carefully remove the plant from its current home inspecting for signs of damage or pests on its roots before transitioning to the new pot. 

Propagating Euphorbia Lophogona

Propagation is quite an effortless task, that is best accomplished through cuttings. A healthy parent plant, gloves, and a sharp, sterilized instrument are all you need to start the propagation process.

Clean and sterilize your gardening tools before starting stem-cutting propagation to prevent the spread of diseases among plants.

Simply cut off a stem about 2-5 inches long from the mother plant, making sure it’s a healthy mature branch.

After acquiring a cutting, allow it to dry for several days before planting in sandy soil or potting mix meant specifically for succulents. This drying period helps to form a callus on the cut end that can prevent disease and rot once planted.

The newly propagated Euphorbia lophogona requires minimal care initially. It should be kept slightly moist until its roots are firmly established in the new environment which typically takes between two weeks to one month depending on temperature and sunlight exposure.

During this rooting phase, make certain not to let these young plants experience frost as this could lead to serious root damage.

Growing in well-draining soil is crucial since damp conditions might trigger root rot which would inevitably kill your plant even before it can grow fully. 

Common Pests and Issues

Mealybugs and spider mites are the most common pests of Euphorbia plants. They will eat the plant causing gradual deterioration and eventually killing them. Catching them early is your best chance of controlling them as they populate rapidly. Insecticidal soaps and oils are good nontoxic remedies.

Excess moisture can lead to the development of root rot and fungal diseases. Too much water can become trapped around the roots, which leads to decay and ultimately, death of the succulent. Address the plant’s growing conditions before restoring to the use of fungicides.

Another prevalent issue arises from an imbalance in nutrients due to incorrect fertilization. A low-nitrogen fertilizer helps maintain healthy growth without causing harm or unnecessary stress to your Euphorbia lophogona.

Wrapping Up

Proper maintenance of Euphorbia lophogona ensures a long, healthy life for this succulent. Regular watering schedules, appropriate sunlight, and nutrient-rich soil are crucial aspects of its care routine.

Be sure to propagate your plant in the optimal seasons using cuttings. Keep it protected from harsh frosty conditions but don’t forget it also needs well-drained soil to prevent root rot issues.
