At first spherical, the Euphorbia obesa becomes taller with age. The plant has a long tap root. As with the other Euphorbias, its sap is poisonous.
Although this Euphorbia is very common in cultivation, it is almost extinct in the wild, mostly through over-collection and loss of habitat.
Blooming Habits:
The tiny flowers are delicately scented. They form at the top of the plant (This picture was taken at the end of March in Phoenix.) This species is dioecious (meaning that there are male plants, and female plants).
Culture:
This species is dormant in winter, keep it totally dry at or around 40°F (4°C).
