Globe Centaurea, also called Great Golden Knapweed, is a robust perennial from the Caucasus, introduced to Britain by 1805. Philadelphia nurseryman Bernard McMahon sent seeds to Thomas Jefferson in 1812. The plant forms clumps 3-4’ high with large, thistle-like flowers in early summer. Its chestnut-brown buds open to expose a crown of rich yellow florets.
