MILK THISTLE

Normal/regular weed. Annual Weed/Broadleaf weed

Ecological: Milk thistle establishes dense stands and can take over large areas of pasture, where it can outcompete native and forage species. Social: Dense patches of Milk thistle are difficult to move through. Sharp spines on the plants can injure livestock and people who brush against them.
Economic: Milk thistle is toxic to livestock and outcompetes desirable forage species. When it takes over areas of pasture, it reduces and restricts access to grazeable land for livestock. Milk thistle also provides shelter for pests such as rabbits and pest insects that can further damage nearby crops.

Also known as Saint Marys Thistle, Blessed Milk Thistle and Holy Thistle, it is found in many countries around the world including Australia. It grows freely in New South Wales, Victoria and widespread across the south eastern and south western seaboard of Australia.
