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 provincially regulated and noxious in BC.
About This Species
Myrtle spurge is an escaped garden perennial that likes dry, disturbed soils. 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.
How to Identify
Myrtle spurge’s leaves and stems are a light blue-green color. Its leaves are very sharp and spiral closely around the stem. Plants grow 10 – 15 cm tall and form a low, spreading mound. Myrtle spurge’s flowers are small and yellow.
