Jacobaea vulgaris is a declared noxious weed in many parts of the temperate zone, spreading freely by seed. It has spread rapidly since the middle of the 19th century and is now common from the Americas to Australia and New Zealand..should not be cultivated other than in controlled conditions for scientific research. Ragwort can be eradicated by pulling it up just before it comes into flower, or by cutting it down as the flowers begin to open (this latter may need to be repeated about six weeks later)[
