Plant Profile: Euphorbia royleana

Euphorbia royleana, commonly known as Sullu Spurge, is a deciduous shrub or tree that stands upright and features whorled, succulent branches segmented into distinct parts, along with a robust, hairy trunk. Its stems are equipped with short prickles, giving it a somewhat cactus-like appearance, despite having no botanical relation to cacti. The plant produces large, clustered leaves that emerge during the wet season but quickly drop off. The spines are arranged in pairs, pointing downward and characterized by broad, flat surfaces. While the plant is mildly toxic, its sap can cause skin irritation.

Sullu Spurge is relatively easy to cultivate, thriving in well-drained soil and full sunlight. However, unlike many succulents, it does not fare well during extended dry spells.

In its native habitat of Pakistan, this plant typically grows on dry, rocky slopes at high elevations. In northern India, it serves as a living hedge to help manage livestock.

As for plant health, there are no known issues with diseases or pests affecting Sullu Spurge.
