Summary
editDescriptionCommon Knapweed (Centaurea nigra) - geograph.org.uk - 1451995.jpg |
English: Common Knapweed (Centaurea nigra) Resembling thistles without prickles, knapweed is widespread in grassland and on roadsides. It has hard, knob-like heads, and in consequence is sometimes called hard-heads. The heads are brown-black and made up of many rows of closely overlapping scales, inside which are red-purple fertile florets.
The stems, which are usually swollen and hollow beneath the heads, are wiry, difficult to pick, and unattractive to cattle. This has made the plant a serioys weed of grassland in some areas. Knapweed was once thought to be able to foretell a maidens future. A girl would pick a flower and remove the expanded florets, and then put the flower head inside her blouse. After an hour, she would remove it and if the unexpanded florets had blossomed, it was a sign that the man she would marry would shortly be coming her way. |
