24–36" tall.
Clusters of deep blue pointed flower buds form in early summer and open into powder-blue star-shaped florets held above deep green fine grassy willow-like foliage. Florets form a tight cluster as if the blossoms were held by self-gravitation, giving it a fantastically unusual appearance that is more chaotic than tidy upon close examination. Gorgeous foliage turns gold in the fall. Best planted en masse. Forms a handsome vase shape at maturity. Looks fabulous with catmint and irises.
Adaptable to most garden environments but performs best in full sun to part shade. Plant 12–18" apart in moist slightly acidic soil. Native Midwest to mid-Atlantic. Z3. Maine Grown. (bare-root plant)
