Propagation
Take stem cuttings from spring to summer. Allow the cuttings to dry and form a callus before planting into a very well-drained gritty media.

Division of the clump during spring.

Note:
Care should be taken when selecting a site as all Euphorbia's contain white sap that causes skin and eye irritation. Be certain to wash your hands with soap and water after handling plant material.

Botanic information
Leaf: The dark green slightly succulent oblanceolate to spathulate leaves are up to 40 mm (1⅝ in) long and have an obtuse apex. The downward facing pungent conical spines are arranged in pairs along the undulating margins and are up to 7 mm (¼ in) long.

Flower: The male and female flowers are arranged in a cup-shaped involucre-like organ (cyathia) that has small yellow bracts. The male flower has exserted stamens and the female consists of a 3-celled pistil. The flowers are arranged in a cyme that appears towards the apex of the stem from spring to early summer.

Fruit: The 3-valve brown oval capsule is an explosive schizocarp that is 12 mm (½ in) long by 15 mm (⅔ in) wide and contains the numerous brown seeds that are up to 3 mm (⅛ in) long and wide and are viable but the plant is commonly reproduced vegetatively to maintain true to type.
