Growing Notes

This plant offsets from the base, creating a clump of many heads. Looks best in a hot intense sunny spot.
Take care when pruning, as euphorbias have toxic sap that can cause a skin rash or damage to the eyes (make sure to rinse repeatedly with water if sap gets anywhere near your eyes). This sap also prevents predation of the plant.

Special Interest

It is fascinating that the spines of this plant are actually sterile peduncles, the stem that would usually hold a flower. Many euphorbia have relatively spiny peduncles, but Euphorbia ferox takes it to the extreme!
