Bluish-lilac honeycomb-like flowerheads on slender stems from July to September and hairy dull green leaves. This beautiful native field scabious was once used to treat scabies and other skin ailments - hence its common name. Highly attractive to butterflies and bees it's perfect for naturalising in a sunny wildflower garden, mixed or herbaceous border.
- Garden care: When sowing seeds do not use a fertiliser since wildflowers prefer poor soils. In autumn after flowering cut the faded flowerheads down to the ground and compost the dead stems.
