Black Knight Butterfly Bush is a well branching shrub with a spreading, arching habit that can reach 6-8’ tall if not cut back in late winter. Black Knight Butterfly Bush has willowy grey-green leaves and large fragrant spike-like clusters of deep, nearly black, purple flowers that bloom in summer attracting butterflies. Removing spent flowers can encourage continued blooms until frost. Best performance in sunny well-drained areas.
