Spotted Knapweed

Centaurea maculosa

Spotted Knapweed, like Russian and Diffuse Knapweed, is a member of the sunflower family.  This plant is a simple perennial with a non-branching root system.  Spotted Knapweed is an aggressive competitor and will displace all desirable vegetation in rangelands, meadows, pastures, wildlife habitats, and recreational area.  Diffuse Knapweed is differentiated from the other two species mentioned due to the floral bracts that are stiff and have a dark comb-like fringe giving the appearance of spots.
