Botanical name: Euphorbia trigona ‘Rubra’
Also known as: Red African Milk Tree, Cathedral Cactus

An architectural succulent with upright, three-sided stems flushed burgundy to deep wine red. Small teardrop leaves line each ridge, creating a striking candelabra look that anchors sunny rooms with height and structure. Tough and drought tolerant, it brings bold color and sculptural lines to modern spaces with very little fuss.

☀️ Light: Bright light to full sun indoors. More sun brings deeper red coloration.

💧 Water: Let soil dry out fully between waterings. Water sparingly and even less in winter to prevent root rot.

🌫️ Humidity: Average home humidity is perfect. No boosting needed.

📏 Size: Typically 3–6 feet tall and 1–2 feet wide over time. Columnar, upright habit.

🐾 Pet-friendly?: ❌ Not pet-friendly. Milky sap is toxic if ingested and can irritate skin and eyes.

🪴 Where It Looks Best: Sunny windows, entryways, and minimalist or modern corners paired with terracotta or stone planters.

💡 Pro Tip: Use a very fast-draining cactus and succulent mix and a pot with drainage. Rotate monthly for even color. Avoid temps below 55°F and wear gloves if pruning due to latex sap.
