Blue mist shrub is aptly named as its gray-green foliage is shrouded in a cloud of blue from mid to late summer. It is a well-behaved garden plant that is very attractive to butterflies. 'Dark Knight' has deep purple blue flowers closely spaced on long stems.
A superior selection for its sturdy upright stems, fine threadleaf foliage and deep wine-red flowers that do not become “frosted” in the heat. Sterile flowers bloom all summer; cutting back will encourage rebloom until frost. Beautiful in the perennial garden or as a special accent. A selection from Darrell Probst that is not to be overlooked!
