Jefferson-documented
Globe Centaurea, or Great Golden Knapweed, is a robust perennial from the Caucasus, reportedly introduced to Britain in 1805. The Philadelphia nurseryman Bernard McMahon sent seeds of this species to Thomas Jefferson in 1812. Unlike other thistles, Globe Centaurea is not invasive and is a handsome ornamental in the garden. Flower heads can be easily dried for arrangements. zone3,zone4,zone5,zone6,zone7,zone8,zone9
