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.
