Globe Thistle
Description
Echinops ritro is a clump-forming, 4-foot tall plant with golf ball sized blue flower heads atop stiff, rigid stems clad with deeply lobed, dark green, thistle-like foliage. Globular, thistle-like, deep steel blue flower heads (1-2†diameter) bloom at the stem tops in summer. Coarse, spiny, deeply-dissected, gray-green leaves are white tomentose beneath. Basal leaves grow to 6-8†long, but stem leaves grow shorter. -Missouri Botanical Garden
