Plant Notes:**
Taxonomic Notes:The Centaurea jacea complex which is European in origin is a difficult group due to hybridization, polyploidy, apomixis, and morphological variation (see Keil and Ochsmann [2006] for a brief overview). Keil & Ochsmann (2006) in FNA follow the “traditional approach for North America” and recognize three species (C. jacea, C. nigra, and C. nigrescens) and a nothospecies (C. x moncktonii). This does align (albeit with some modifications) with Fernald (1950) and Gleason and Cronquist (1991). We also follow this approach.
Status:Not Native, Naturalized, GNR (Global Rank)
