Amidst the tranquil alpine meadows of North Tyrol, the Common knapweed (Centaurea nigra) flourishes, its distinctive purple blooms adding vibrant contrast against the backdrop of an ancient hut. A closer look reveals the intricacies of its structure in an X-ray image. In the British Channel islands of Sark, Common knapweed continues to thrive, providing essential nectar for pollinators like the Six-spot burnet moth and Small Copper Butterfly. Evening primrose (Oenothera biennis) also graces these meadows, creating a symbiotic relationship with the knapweed. The beauty of nature lies not only in its picturesque landscapes, but also in the intricate interplay between species.
