The ragged-edged, purple flower heads of Greater knapweed bloom on sunny chalk grasslands and clifftops, and along woodland rides. They attract clouds of butterflies including Common blues, Marbled whites and Meadow browns.

Thriving on chalk and limestone and well-drained soils, the seed heads are likely to attract finches.

The large, bright, pink-purple ‘flowers’ of Greater Knapweed are actually composite flower heads made up of many small ‘florets’ (tiny flowers). The large, ragged, star-like ones sit around the edge of the flower head and are sterile, serving only to attract insects; while the smaller, densely packed florets in the middle are fertile.
