Description
Long, scented panicles of deep-purple flowers make Buddleja davidii Black Knight a vivid summer-to-fall feature for a sunny border. The vigorous, arching shrub carries lance-shaped green leaves with pale felted undersides and draws bees, butterflies, and other pollinating insects.
Allow generous room for its broad mature framework in a wildlife garden, cottage border, or flowering bed. It grows best in full sun or partial shade and moist but well-drained to well-drained soil. Water regularly while the roots establish, then reduce frequency; established plants tolerate dry periods.
Cut the previous season’s branches back to a low permanent framework in early spring, and remove spent flower panicles to encourage another flush. In fertile soil, an annual organic mulch is generally enough without extra feeding.
