Invasive Plant

Cypress Spurge

Euphorbia cyparissias
Warning icon

Warning

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.

About This Species

Cypress spurge was grown as an ornamental but has since escaped into the wild. It prefers sun but tolerates shade as well. It can be found growing in open, disturbed sites like meadows, pastures, and roadsides. It grows quickly and aggressively, releasing chemicals from its roots which stop other plants growing near it. This helps it crowd out native species.

How to Identify

Cypress spurge can be 10 – 60 cm tall with thin, waxy, blue-green leaves 2.5 – 3 cm long that spiral around the stem. The flowers are yellow to green and turn red at maturity.
