Euphorbia acrurensis, commonly known as the Desert Candle, is a tall, columnar cactus-like succulent native to the deserts of North Africa. Known for its striking, upright growth and thick, spiny stems, this plant can grow quite large and is perfect for those looking to add a dramatic, low-maintenance plant to their collection. Its unique appearance makes it a popular choice for rock gardens, xeriscaping, or as a standout feature plant in dry landscapes.
Full Botanical Name: Euphorbia acrurensis
Common Names: Desert Candle, African Candelabra

Growing Conditions in Native Habitat: Grows in dry, arid conditions in rocky, well-drained soils, often found in desert regions where rainfall is minimal and the soil is sandy or gravelly.
Care Guide
Care Guide:
Light: Prefers full sun to thrive. It can tolerate partial shade, but for optimal growth and vibrant coloration, it should be exposed to direct sunlight for several hours a day. A sunny windowsill or outdoor spot with ample light is ideal for this plant.
Ideal Room: Ideal for sunny spots such as windowsills, patios, or garden spaces. It can also be kept in containers, making it suitable for both indoor and outdoor environments.
Feeding: Fertilize sparingly during the growing season (spring and summer) with a diluted, balanced cactus fertilizer. Over-fertilizing can lead to weak growth, so it's best to fertilize every 6-8 weeks. Reduce feeding in the fall and winter months when growth slows.
Humidity: Prefers low humidity, typical of desert environments. It will thrive in dry indoor spaces and does not require additional moisture in the air.
Ideal Temperature: Best kept between 70°F and 90°F (21°C to 32°C). It is sensitive to frost and should be protected from temperatures below 50°F (10°C) to prevent damage.
Watering: Water sparingly, allowing the soil to dry completely between waterings. As a drought-tolerant succulent, Euphorbia acrurensis is more tolerant of underwatering than overwatering. Ensure the plant has good drainage to avoid water accumulation, which can lead to root rot.
Pet/Child Safe: Toxic to pets (cats and dogs) and children if ingested, so keep out of reach of animals and young children. The plant's sap can also be irritating to the skin and eyes, so wear gloves when handling.
Soil Type: Use a well-draining cactus or succulent mix. A mix designed specifically for cacti will ensure proper drainage and prevent water retention around the roots.
Propagation: Propagate by stem cuttings. Simply cut a healthy stem, let the cut end callous over for a few days, and then plant it in dry, well-draining soil. Rooting hormones can be applied to encourage faster rooting.
Eventual Height and Spread: Typically grows up to 10-12 feet (3-3.6 meters) tall, with a spread of about 3-4 feet (90-120 cm). It forms a tall, columnar shape with dense, spiny stems, making it a bold feature in any landscape.
Growth Rate: Slow-growing. Euphorbia acrurensis will grow steadily over time, but it does not require frequent maintenance or repotting.
Pests and Treatment: Generally pest-resistant, but may occasionally attract mealybugs or aphids. Treat infestations with neem oil or insecticidal soap to keep the plant healthy.
Repotting: Repot every 2-3 years or when the plant becomes root-bound. Choose a pot that is slightly larger than the current one and ensure it has good drainage to promote healthy root growth.
Pruning: Prune dead or damaged stems to maintain the plant's appearance. Euphorbia acrurensis does not require much pruning, but removing unwanted or unhealthy growth will help the plant thrive.
Air Purification: Like many succulents, Euphorbia acrurensis helps improve indoor air quality by absorbing carbon dioxide and releasing oxygen, making it a beneficial addition to your home or office.
Folklore: Euphorbia species, including Euphorbia acrurensis, are often associated with resilience and endurance due to their ability to survive in harsh desert conditions. They are seen as symbols of strength and protection in many cultures.
