The Euphorbia Trigona, commonly known as the African Milk Tree, is a distinctive and resilient succulent that originates from Central Africa. It is appreciated for its architectural form and ease of care, making it a popular choice for both indoor and outdoor plant enthusiasts. Here’s an overview of the Euphorbia Trigona:
Description:
Scientific Name: Euphorbia trigona
Common Names: African Milk Tree, Cathedral Cactus, Friendship Cactus
Appearance: Euphorbia Trigona is characterized by its upright, columnar stems that can grow several feet tall. The stems are triangular in cross-section, with three distinct sides lined with ridges. Small, spiny thorns protrude from these ridges, and between each pair of thorns, there are small, oblong leaves. The plant can range in color from bright green with white patterns (Euphorbia Trigona) to a deep red or burgundy (Euphorbia Trigona ‘Rubra’ or ‘Royal Red’) variety.
Size: It can grow up to 6-8 feet (1.8-2.4 meters) tall indoors with proper care, and even taller when grown outdoors in suitable climates. The width is generally much less, making it a tall, narrow plant.

Benefits
Aesthetic Appeal: With its tall, columnar growth and unique shape, Euphorbia Trigona adds a dramatic, architectural element to any space. The contrast between the green and burgundy varieties offers visual interest.
Low Maintenance: Its drought tolerance and adaptability make it a great choice for beginners or those who may forget to water their plants regularly.
Air Purification: Like many succulents, it contributes to improving indoor air quality.
Plant Care
Care Requirements:
1. Light:
Thrives in bright, indirect light to full sunlight. A sunny window is ideal for indoor growth. It can adapt to partial shade but may not grow as vigorously.
Outdoors, it should be placed in a location with plenty of sunlight, but it can tolerate some afternoon shade in very hot climates.
2. Watering:
Water sparingly, allowing the soil to dry out completely between waterings. Overwatering is a common issue and can lead to root rot.
During the growing season (spring and summer), water more frequently, about once every 2-4 weeks. In the dormant season (fall and winter), reduce watering significantly.
3. Temperature:
Prefers warm temperatures, ideally between 65-80°F (18-27°C).
It is not frost-tolerant and should be protected from temperatures below 50°F (10°C). Prolonged exposure to cold can damage the plant.
4. Humidity:
Euphorbia Trigona does well in typical household humidity levels. It does not require high humidity and can tolerate dry air, making it suitable for most indoor environments.
5. Soil:
Requires well-draining soil to prevent water retention and root rot. A cactus or succulent potting mix is ideal. You can also mix standard potting soil with sand, perlite, or pumice to enhance drainage.
Ensure the pot has drainage holes to allow excess water to escape.
6. Fertilization:
Fertilize sparingly, using a balanced, diluted liquid fertilizer during the growing season (spring and summer), about once a month.
Fertilization is not necessary during the fall and winter months when the plants growth naturally slows.
7. Propagation:
Easily propagated through stem cuttings. Allow the cut end to dry and callous over for a few days before planting it in well-draining soil.
Use gloves when handling the plant, as the sap is toxic and can cause skin irritation.
Common Issues:
Yellowing or Dropping Leaves: Often a sign of overwatering or insufficient light. Check the soil moisture and ensure the plant receives enough light.
Stem Rot: Caused by excessive watering or poor drainage. Ensure the soil is well-draining and the pot has adequate drainage holes.
Pests: Generally pest-resistant, but can occasionally attract mealybugs or spider mites. Regular inspection and treatment with insecticidal soap can help manage infestations.
