Field Scabious ( Knautia arvensis (L.) Coult)
Field Scabious is a perennial that grows in grassland on well-drained, especially basic soils. It is a member of the teasel family with a deeply-penetrating, somewhat woody taproot. Lower leaves are pinate, lance-shaped, with toothed margins, and form a basal rosette. Upper leaves are stalkless and pinnate with 3-6 segments at each side with a terminal lobe.
The flower heads are usually pale lilac or light blue and comprise about fifty densely packed purplish-blue florets. The flowers resemble a round pin cushion.
