Its unique structure, vibrant green stems, and low-maintenance care requirements make it a favorite among plant enthusiasts.

History and Origin

Native to Central Africa, the African Milk Tree thrives in arid and semi-arid climates, particularly in regions with well-draining soil. The plant's resilience to drought and heat made it a staple in traditional African gardens. It has since been popularized worldwide, often grown indoors or as a striking addition to xeriscaped gardens.

• Spines and Leaves: Each segment is adorned with small, sharp spines, and tiny, oval-shaped leaves sprout from the sides of its ridges.

Nutritional Benefits

Cultivation and Care Tips

To ensure your African Milk Tree thrives, follow these care guidelines:

• Light: Prefers bright, indirect light but can tolerate some direct sunlight. Avoid placing it in low-light conditions.

• Fertilizer: Feed with a diluted cactus fertilizer once a month during the growing season (spring and summer).
• Repotting: Repot every 2-3 years or when it outgrows its container.
