Spotted knapweed, also known as Panicled knapweed
Spotted knapweed, or Centaurea stoebe, is known throughout the United States as a particularly harmful noxious weed. It crowds out native grasses, which increases soil erosion and water runoff. There is some control of spotted knapweed that can be done by grazing sheep on problem areas, as all growth stages of this plant are nutritious to sheep.
