In Britain and America, it is often found as a hybrid of black knapweed, Centaurea nigra.[2] Unlike the black knapweed, the flower heads always look as if they are rayed, forming a more open star rather than a brush-like tuft.
Centaurea × moncktonii is a fertile hybrid between black knapweed and brown knapweed.[3]
