Comments: 'Black Knight' is a butterfly bush cultivar which features almost black flowers. It is a deciduous shrub with an arching, spreading habit. Features spike-like 4 to 10 inch long terminal clusters of very dark purple flowers which bloom from June to September and sometimes to first frost. Flowers are fragrant, and, as the common name suggests, very attractive to butterflies. Willowy gray-green foliage. Popular fresh cut flower.
