Black Knight Butterfly Bush

Black Knight Butterfly Bush (Buddleja davidii 'Black Knight') is a vigorous deciduous shrub prized for its striking deep purple-black flower spikes that bloom throughout summer. Native to China, this cultivar thrives in USDA hardiness zones 5-9 and reaches 4-8 feet tall with a 4-6 foot spread. Requiring full sun exposure, it produces highly fragrant blooms that attract butterflies, bees, and other beneficial pollinators. Fast-growing and low-maintenance, Black Knight makes an excellent choice for adding vertical interest, color, and wildlife activity to gardens and landscapes.
