Description: Dark Knight (also commonly called blue spirea, blue mist, or bluebeard) is a low-mounded, deciduous shrub that is valued for its aromatic foliage and late summer flowers which are said to resemble clouds of blue smoke or mist. 'Dark Knight' features a profuse, shrub-covering bloom of fragrant, deep bluish-purple flowers in large clusters from late summer into fall. Ovate to lance-shaped, dull green leaves (to 1.5" long) are silvery below. Foliage is aromatic when brushed with a hand. Flowers are very attractive to butterflies and other beneficial insects.
