Add color and butterflies to your garden with the Black Knight Butterfly Bush! Butterflies and hummingbirds are drawn to the sweet nectar that is produced from its fragrant blooms. Dark violet-purple flower spikes appear on cascading stems from early summer until fall. This shrubs arching, spreading shape is enhanced by its outstanding colorful flowers and its willow-like green foliage. Popular in cut flower arrangements, the Black Knight is also a good choice for borders, containers, butterfly gardens, hedges or landscape accents. Spent flower heads can be removed to encourage additional blooming. Hardy, showy and low maintenance!
