Centaurea nigra is a species of flowering plant in the family Asteraceae, and is also known as lesser knapweed, common knapweed, black knapweed and bell weed.
It is native to central Europe, and has been introduced to temperate North America and Australasia, where it is usually regarded as a noxious weed due to its fast spread, hardiness and competitive potential.
