Also known as Globe Thistle. Echinops bannaticus is an erect, clump-forming perennial globe thistle that typically grows to 4’ (less frequently to 6’) tall on stiff, sometimes branching stems. It is native to southeastern Europe. Spiny, deeply-dissected leaves (to 14” long) are rough green above and downy-white below. Globular, thistle-like, gray-blue flower heads (to 2” diameter) bloom at the stem tops in summer. ‘Blue Glow’ improves on the species by producing intense steel blue flowerheads.
