The African Milk Tree is a striking, fast-growing succulent often mistaken for a cactus due to its upright, thorny stems. Characterized by its distinct three-sided (trigona) branches, it features vibrant green stalks frequently accented by deep reddish-purple hues on new growth and small, tear-shaped leaves along the ridges. While it reaches impressive heights as a vertical accent, it remains a popular choice for both indoor containers and temperate gardens. This resilient species thrives in bright, indirect light and requires a well-draining substrate, allowing the soil to dry completely between moderate waterings to maintain its architectural integrity.
