Prickly, thistle-like foliages is a deep green with silvery undersides is one pretty aspect of the blue echinops, but the showstopper is the rounded blue flower clusters in late summer. A upright, clump-forming perennial, it hails from southeastern Europe eastward into central Asia.
The dark green leaves are coarsely lobed, looking like leaves of a thistle or pointy-leaf oak. There are white fibers on the leaf edges at times and the undersides are a downy white-gray. In late summer stems are topped with a globe-like cluster of tiny dark blue flowers that age to lighter blue, attracting bees and butterflies. The spent flowers turn tan, creating an architectural white, tan and dark brown globe. Seeds are shed and will germinate nearby.
Grow blue echinops in full sun to partial shade in nearly any average garden soil that does not become overly wet. The blue flower balls make pretty cutflowers, as does the foliage; dried flower balls are usable in dried arrangements.
