Herbs Weed profiles & Native alternatives
I’M A WEED
Erect, stiff perennial herb with multiple stems to 0.7 m arising from a long strong tap root. Bright green leaves, often tinged with red, are thick and fleshy, crowded along stems. Flowers from September to May. Common in foredunes.
Threat / Problem
• Spreads rapidly forming dense patches in dunes and salt marshes, displacing native vegetation and has properties that inhibit germination of native plants
• Can change the shape of dunes making them more prone to erosion and impacting beachnesting birds
• Produces toxic milky sap that irritates the skin and eyes
• Seeds scatter when ripe fruits burst open, also spread by vehicles, birds, ants and garden waste dumping. E. paralias seeds are very salt tolerant and buoyant. Seeds may be viable for up to 2 years in salt water.
• Hand pull (wear protective clothing). Ensure taproot is removed. Spray with broadleaf herbicide while actively growing.
