Scotch thistle, known scientifically as Onopordum acanthium, is a tall, spiny plant native to Europe and Asia. It features large, lobed leaves and striking purple flowers that bloom in summer. The plant can grow up to 2 meters in height and is often found in disturbed areas, such as roadsides and fields. This thistle is recognized as the national emblem of Scotland, symbolizing resilience and strength. While it can be visually appealing, Scotch thistle is also considered an invasive species in some regions, as it can outcompete native plants and disrupt local ecosystems.
