Globe Thistle Blue Glow, scientifically known as Echinops bannaticus, is a fantastic flowering perennial that features a showy, textural, floral element to liven any garden bed. Vibrant blue, globe shaped flower heads appear to hover over gray-green, well formed, 3' - 4' foot tall bushes with prickly and deeply cut foliage. An enchanting addition to any garden style, Blue Glow creates a touch of whimsy and allure. The 2" inch, vivid blue flower heads are a party all their own for friendly pollinators. In arrangements, they make an outstanding cut flower used either fresh or dried. Winter hardy to zone 3, this variety thrives in a sunny location and tolerates drought and poor soils like a champion. Introduced in 1832, this garden charmer has been a well loved cutting garden performer for over 185 years! Freely self sows seeds. To avoid over spreading, cut all the blooms before they mature to seed. Packet: 25 seeds.
