Knautia arvensis

This has the classic button-like flowers that are characteristic of scabious. The flowers are coloured blue-lilac and are held way above the foliage on slender branching stems. The small flowers are very pretty with a bouffant centre of paler petals and masses of slim petals with rounded ends round the outside. Loved by bees and a feature from June through to September. The foliage mound is somewhat untidy and the leaves will have various shapes, sometimes entire, sometimes with paired lobes and a larger pointed terminal leaf. It is a European native that has established itself in parts of the new world.
