This well-behaved hearty perennial delivers a long-lasting violet-blue mist comprised of tiny flowers that profusely stud branching silver spikes, galvanizing hummingbirds, butterflies and bees for months. Undaunted by deer, rabbits, cold weather and dry locales, the firm, erect steel-hued stems are clothed in tasteful, serrated gray-green leaves. Smaller than the species, with a little less spread, low maintenance ‘Blue Steel’ lends stately soft-looking accents to mixed borders, cottage gardens and Mediterranean plantings.
Size: 2-1/2' – 3' 0" high x 2' 0" – 2-1/3' wide.
Hardy to zone 4.
