Meadow knapweed (Centaurea × gerstlaueri), also known as hybrid knapweed or protean knapweed, is a fertile hybrid between black knapweed (Centaurea nigra) and brown knapweed (Centaurea jacea).[1] The taxonomic status of the species is uncertain, and meadow knapweed has been variously described as different species.
