Carnation Spurge is a Mediterranean plant with a tendency to globally spread in areas with similar climate. It is a problem weed in Australia, specifically Western Australia, South Australia, and Victoria. Carnation Spurge grows rapidly and is a prolific seed producer, able to create thickets that push out native species even in undisturbed bushland, open woodlands, coastal and riparian habitats. The seedheads explode when they mature, spreading efficiently in the nearby areas, and are also carried long distances by water or vehicles. Like with many other Euphorbia species, the milky sap of this plant is toxic and it deters herbivores from consuming it.
