An upright, succulent tree with a dark green crown which is well rounded and often shaped like a hot-air balloon. Grows up to 12 m. The branches are segmented with spines running along the ridges of the segments. It produces small, greenish yellow flowers on the ridges of the topmost segment of every branch from autumn to winter. The fruit is a round 3-lobed capsule which turns red to purple when ripening. These plants are easy to grow and make a wonderful addition to a succulent garden or rockery. As it is a succulent it needs little to no maintenance, being a very drought hardy plant. It does best in the open sun. Because of its poisonous latex/sap no pests seem to bother these trees. The latex of this tree is extremely toxic and can cause severe skin irritations, blindness and severe illness to humans and animals if swallowed. Grass is soaked in the latex and used as fish poison. it is also used medicinally in small amounts to treat cancer. The wood is used for boats, doors and planks. The trunk is first burnt to solidify the latex before it is cut as the latex in the eyes can cause blindness. It can be used for hedging and screening and an effective thorny barrier. It is frost tender. The fruit is enjoyed by monkeys while porcupine and cane rats eat the roots. This protective plant is used in a ritual cleansing of a home after childbirth. The name is derived from the Greek eu=well and phorbe=pasteur referring to the Greek physician Euphorbus.
