Common Knapweed (Centaurea negra)
Collins, 260; Readers Digest,
This is a large plant with strong stems and long stalked leaves. The stem leaves are stalkless. It flowers in our hedgerows from June to September. It is extremely pretty when in flower, the flower head having the air of a thistle head. It derives its name from the word ‘knap’ meaning a knob.
According to folk law Knapweed can be used to foretell a maiden’s future. The girl has to pick the expanded florets off a flower head and then put the remainder of the flower head inside her blouse. After an hour she should take it out again and examine it. If the previously unexpanded florets have now blossomed, it is a sure sign that the man she will marry will shortly be arriving.
