Scientific Name: (Centaurea stoebe)
Spotted Knapweed
• A very aggressive species that can infest large areas quickly.

• Native to central Europe.

• Forms a symbiotic relationship with a certain fungus in the soil, which "steals" carbon from surrounding plants, reducing their ability to compete.

• Knapweed loves disturbed soils and is often the first to establish.

• "Motorized vehicles are a huge contributor to the spread of knapweed. Nearly 2,000 seeds may be caught underneath a vehicle after driving through one knapweed patch. Up to 10% of those seeds can be stuck there ten miles down the road."
