Globe thistle's bristling balls of purple-blue are all show - only prickly in appearance but not to touch. The showy spheres bloom mid-summer into fall, then grey into winter interest. The wealth of pointed green leaves give rise to upright stalky stems, for back of border height. These cool blooms are a favourite complement to hotter summer and fall blooming companions. An easy, drought tolerant perennial!
