📌 Product Description

Euphorbia trigona ‘Rubra’ is a dramatic red-flushed form of the African Milk Tree, prized for its striking burgundy to deep red stems. The triangular, ridged stems feature short paired spines and small leaves along the edges, creating a bold architectural silhouette.

Colour intensity deepens in bright sunlight and cooler conditions, making this an eye-catching feature in modern gardens and decorative containers. Although commonly mistaken for a cactus, it is a true Euphorbia and shares the same hardy, drought-tolerant characteristics as the green form.

⚠️ The white milky sap is toxic and may irritate skin and eyes. Handle with care and keep away from pets and children.
