'Black Knight' is a cultivar of Buddleia davidii, commonly called butterfly bush, that features almost black flowers. It is a deciduous shrub with an arching, spreading habit that typically grows 180-250 cm tall if not cut back hard in late winter and 120 to 150 cm tall if cut back. It features spike-like 10-25 cm long terminal clusters of very dark purple flowers that bloom from June to September and sometimes to first frost. Flowers have a honey-like scent and are attractive to bees and butterflies.
