Scientific literature: Very Sparse (0 studies) · ★☆☆☆☆

Centaurea solstitialis, commonly known as yellow star-thistle, is a highly invasive perennial herb native to Eurasia. This plant is easily identified by its bright yellow, thistle-like flower heads that bloom throughout the summer months. The striking appearance of the flower often masks the significant ecological damage the species causes to local biodiversity. As it spreads rapidly across grasslands and pastures, it outcompetes native vegetation for vital resources. Understanding the lifecycle and floral characteristics of this weed is essential for effective management and control.
