In the wild, it is endangered because of over-collection and poaching, because of its slow growth, and the fact that the pod contains only 2 to 3 seeds. However, it is widely cultivated in botanical gardens.
Euphorbia obesa resembles a ball, thornless and decorative. It is commonly known as 'baseball plant' due to its shape. Its diameter is between 6 cm and 15 cm depending on its age. Young Euphorbia obesa's are spherical, but become cylindrical with age. They contain water reservoirs for periods of drought.
It almost always shows 8 ridges adorned with small deep gibbosity regularly planted on the edges. It is green with horizontal lighter or darker stripes. In the wild, and with exposure to direct sunlight, it shows red and purple areas.
As in all Euphorbia species, the latex is toxic.
