3. Spotted Knapweed
Spotted knapweed is a purple wildflower found on the roads and open fields of Toronto. It is considered to be an aggressive weed as it tends to overrun other plants in its area.
Other than aggressively spreading, spotted knapweed has a quality that uses its own chemicals to change the soil composition, making it difficult or impossible for other plants to grow.
