Echinops sphaerocephalus
Great globe thistle is a bold, tall species with silvery white flower heads on stout, gray stems. It is taller and more vigorous than small globe thistle and suits open, sunny sites. Plants adapt to poor, dry soils after establishment and need sharp drainage. Bloom is mid to late summer on stems that rise above many border perennials. Heads dry well for winter texture.
