Knautia arvensis

Glorious scabious-like, pin cushion blooms are borne on the lax stems of this wildflower, in soft shades of lilac-blue. The nectar-rich blooms are a magnet for bees and butterflies and are produced in abundance from July to early autumn. Grow field scabious in borders and wildlife gardens where their tall swaying stems will create an informal display, or use them as cut flowers for a vase indoors. Height: 1.5m (5'). Spread: 45cm (18).
