Euphorbia jansenvillensis (WA Prohibited)

Euphorbia jansenvillensis is a spiny, clump-forming succulent species endemic to the Eastern Cape of South Africa, particularly near the town of Jansenville, after which it is named. It grows on arid, rocky slopes and in well-drained soils, often exposed to full sun. The plant forms dense clusters of upright to slightly arching grey-green stems with numerous prominent ridges. Each ridge bears paired reddish to grey spines. Unlike some other columnar Euphorbias, the stems of *E. jansenvillensis* often exhibit a slightly constricted, segmented appearance. Small yellow-green cyathia are produced near the upper stem margins during the growing season.

Care Tips:

• Light – Prefers full sun to bright filtered light; promotes compact growth and healthy spination
• Water – Water sparingly; allow soil to dry thoroughly between waterings
• Humidity – Requires dry air; avoid high humidity and stagnant conditions
• Media – Use a well-drained cactus mix with coarse sand or pumice
• Temperature – Maintain above 10°C; not frost-tolerant
• Fertiliser – Feed during active growth with diluted cactus fertiliser
• Repotting – Repot only when rootbound or when soil has broken down

Additional Notes:

• Known to be toxic
