Euphorbia lactea 'Cristata'
Common Name: Brain Cactus

Euphorbia lactea 'Cristata', often nicknamed the Brain Cactus, is a surreal, sculptural succulent that forms ruffled, fan-shaped crests resembling coral or brain tissue. Its wavy, ridged edges grow in wild, undulating patterns—each one unique—making this plant a favorite among collectors of strange and stunning specimens.

Usually grafted onto a strong rootstock like Euphorbia neriifolia for stability, this crested form is low-maintenance and thrives on minimal water and bright, indirect light. Some specimens also display gorgeous variegation with shades of green, white, pink, or purple depending on light and stress levels.

☀ Light Requirements
Prefers bright, indirect sunlight or filtered light. Too much direct sun can scorch the crest, especially on variegated specimens. Indoors, a south- or east-facing window is ideal.

💧 Watering Needs
Water sparingly—only when the soil is completely dry. Like all Euphorbias, this plant is extremely drought-tolerant and prone to rot if overwatered. Reduce watering in winter.

🌡 Temperature Tolerance
Keep above 50°F. Not frost-tolerant. Protect from cold drafts and wet conditions. For winter shipping, we recommend adding a [Heat Pack].

⚠ Note:
This plant produces a milky latex sap when damaged, which can irritate skin and is toxic if ingested. Handle with care and keep out of reach of children and pets.
