Spotted Knapweed is a perennial flowering plant native to Europe and Asia. It typically grows between 1 to 3 feet tall and features distinctive purple flowers with black-tipped bracts. The plant has a deep taproot and can spread rapidly, often forming dense stands that outcompete native vegetation. This invasive species thrives in disturbed areas, such as roadsides and pastures, and can negatively impact local ecosystems. Its ability to produce a large number of seeds and its resistance to many herbivores contribute to its spread, making it a challenge for land management and conservation efforts.
