Centaurea pratensis or C. debeauxii L.
Meadow knapweed is a perennial plant of European origin that grows up to 3 ½ feet tall. Its leaves are long, compared to other knapweeds, and the margins may be either entire or toothed. It has large, pink flowers with short, woody bracts. The flowers resemble those of spotted knapweed, although they are generally larger. Meadow knapweed reproduces both by seed and from the crown of the plant and will grow in a variety of environments where it can displace native vegetation. Given an opportunity, it will spread further, forming a near monoculture and rendering the land unfit for wildlife.
