CENTAUREA
Commonly known as Knapweed
Genus of about 650 species of annuals, perennials and subshrubs widely found in dry sites, rocky mountain slopes, subalpine meadows, woodland and sand dunes mainly in Europe and the Mediterranean.
Some Knapweeds in the wild can be invasive but garden forms are ornamental and all are beneficial to insects.
In the UK the common C. nigra, Hardhead, can be dried and flower tops make a pale yellow-green dye.
The native perennial Greater knapweed, C. scabiosa can be found mainly in the south and east of England in hedgerows, on roadsides and in dry grassland.
