Centaurea virgata
 
Rosette
The rosette and stems have deeply lobed leaves.
Adult

This long-lived perennial grows 12 to 18 inches tall.
Flower

Flowers are rose to pink. It is often confused with diffuse knapweed, but differs in that the toothed flower bracts are curved outward, and are not laterally toothed. Bloom occurs in early to mid-summer.
Squarrose knapweed is a native plant of the eastern Mediterranean area. It is very competitive on rangelands. Knapweed releases a chemical substance reducing competing vegetation.
