Euphorbia pillansii has a wide distribution in the arid areas of the Western Cape Province from the district of Ladismith westwards towards the Ceres district.
This unisexual Euphorbia with gray-green stems grows to a height of about 30 cm. The peduncles are forked and persistent performing the function of spines after the seed has been dispersed.
The plants flower in spring making small yellowish cyathia.
The cultivation of Euphorbia pillansii is relatively easy. A well drained loamy soil with occasional watering is best. Although the plants grow in the winter rainfall area, rain in habitat is scarce and occasional summer thunderstorms also occur.
