Euphorbia lactea 'Cristata Variegata' - The Coral Cactus (WA Prohibited)

Euphorbia lactea ‘Cristata Variegata’ is a beautiful cultivar of the species Euphorbia lactea, native to tropical regions of India and Sri Lanka where it grows in warm, dry environments. This crested form develops a coral-like fan of ridged growth along a flattened stem, giving rise to its common nickname “coral cactus.” Contrary to this nickname, it is not a cactus but a succulent belonging to the Euphorbiaceae family. The crest is patterned with irregular green, white, and cream variegation, often flushed with pink or purple on the edges in bright light or cooler weather. Its unusual form and slow growth make it commonly grafted onto a hardier Euphorbia rootstock to ensure stability and vigour.

Care Tips:

• Light – Provide bright, indirect light or filtered sun; avoid harsh midday sun that can scorch the pale variegated tissue.
• Water – Water sparingly, allowing the soil to dry thoroughly between watering; Euphorbia are sensitive to overwatering.
• Humidity – Thrives in low humidity environments.
• Media – Use a gritty, free-draining cactus and succulent mix to support healthy root development.
• Temperature – Grow at 15–30 °C; protect from frost and prolonged cold conditions.
• Fertiliser – Apply a diluted, balanced fertiliser during active growth, avoiding high nitrogen levels.
• Repotting – Repot every 2–3 years or when the rootstock fills its container, handling the crest carefully to prevent damage.
