The Brief and Glorious History of the Purple Peas

Centaurea cyanus, the intrepid explorer of European origin, has spread its floral wings, venturing beyond borders like a botanical Marco Polo. Once a British and Irish darling since the Iron Age, now a scarce commodity, shrinking from 264 sites to a scant trio in 50 years! Was it the allure of foreign lands or just a case of floral wanderlust? Its Latin label, centaurea, nods to Chiron, the legendary centaur, who sought solace in its healing embrace after a Hydra-induced mishap. A plant with a mythic reputation indeed!
