- Description
-
Sullu spurge is an erect, deciduous, flowering shrub or tree with whorled, succulent, segmented branches and a stout, hairy trunk. It is armed with short prickles along its stems. It has a cactus-like appearance, although it is unrelated to cactus. Leaves are clustered and large and appear during the moist season and soon fall. Spines are downward-pointing pairs with broad flat faces. The plant is mildly toxic and the sap can irritate skin and eyes.
The plant is easy to grow preferring well-drained soil and full sun. Unlike most succulents, the Sullu spurge does not tolerate long periods of drought.
In its native Pakistan, it is often found on dry and rocky slopes at high altitudes. It is used as a living hedge to control livestock in northern India.
