Centaurea benedicta

Centaurea benedicta (L.) L. (syn.: Cnicus benedictus L.) (Medit., Portugal) – A rare and ephemeral, much decreasing alien. First recorded in 1886 in Leuven and 1896 in Berg. Subsequently also seen in Virton. Most recently found in Marchienne-au-Pont in 1951 (waste land) and Kortrijk in 1953 (potato field).
Early records were usually made in or near gardens. Centaurea benedicta was formerly sometimes cultivated as a medicinal herb which may explain these occurrences.
