Field scabious (Knautia arvensis) also known as Blue buttons or pincushion scabious, invades roadsides, pastures, and fields where it replaces desirable vegetation. The flowers of field scabious range from violet-blue to white in colour and are similar in shape to red clover flowers. All plant parts are covered in stiff hairs. Leaves are deeply divided and they decrease in size as you move toward the shoot. For more identification tips and management options visit the Weeds BC fact sheet.
