BUTTERFLY BUSH BLACK KNIGHT

Description

'Black Knight' is a butterfly bush cultivar which features almost black flowers. It is a deciduous shrub with an arching, spreading habit which typically grows 6-8' tall if not cut back in late winter and 4-5' tall if cut back. Features spike-like 4-10" 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. Easily grown in average, medium, well-drained soil in full sun. Becomes weedy and sparse with diminished flowering performance if not grown in full sun. Does poorly in wet conditions.
