Echinops are not thistles despite their common name, Globe Thistle. Magnificent, steel blue/purple mace-like heads above deeply serrated grey-green leaves. A bold, tall plant Echinops Ritro is highly ornamental. Silvery foliage is deeply cut, shaped like lances. Appears as though the foliage is prickly, but actually the undersides are downy. Provides carefree late summer color. Does well in any soil and attracts Bees and Butterflies. Heat and cold tolerant zone 3-8. Excellent cut flower for arrangements or dry flower.
