Euphorbia trigona ‘Rubra’, known as the Red Triangle Euphorbia, is a striking succulent that brings bold colour and architectural form to your indoor plant collection. With its upright, triangular stems in shades of deep red and burgundy, this plant offers a sculptural silhouette that adds height and drama to bright interiors while creating a modern, clean aesthetic in your living space.
The stems of Euphorbia trigona ‘Rubra’ are lined with small spines along the ridges and dotted with slender, teardrop-shaped leaves that often carry the same rich red tones, adding further depth to the plant’s appearance. Its colour intensifies in bright light, making a sunny windowsill or bright room the perfect spot to help it maintain its vibrant hue. As it grows, this Euphorbia develops into a branching, bush-like shape that becomes a statement feature without overwhelming your space.
Native to Central Africa, this plant thrives in warm, bright conditions and prefers indirect light with some gentle direct sun. Like many succulents, it enjoys a well-draining cactus or succulent compost and should be watered sparingly, allowing the soil to dry out completely between waterings. Overwatering can lead to root rot, so it’s best to err on the side of underwatering, especially during the cooler months when growth naturally slows.
Euphorbia trigona ‘Rubra’ is highly drought-tolerant and requires minimal feeding, but if desired, a diluted cactus fertiliser can be used during the growing season to support healthy growth. It prefers temperatures between 18–26°C and should be protected from frost, making it ideal for indoor cultivation in the UK.
