Myrtle spurge

Euphorbia myrsinites
Warning icon


Myrtle spurge is toxic to humans, livestock and wildlife when consumed, or when its sap (latex) contacts skin. The sap causes nausea, vomiting and diarrhea when eaten. It can cause blindness if it gets in people’s eyes and skin contact causes redness, swelling and blisters. This plant is recognized as invasive and toxic in BC.

About This Species

Myrtle spurge (Donkey tail, Blue spurge) is a short, creeping escaped garden perennial introduced from Europe. It likes dry, disturbed soils where it grows quickly and aggressively, releasing chemicals from its roots which stop other plants from growing near it. This helps it crowd out native species. Myrtle spurge reproduces by seeds, but roots fragmented by cultivation can also produce new plants.
