It’s finally here: an improved ‘Dark Knight’! Darkest Night ® buddleia has been a long time coming. This new selection offers darker flowers and a much more refined habit than the former. The large, fragrant flowers are a deep, rich purple, adding some drama to any landscape or garden. Like other buddleia, it is heat and drought tolerant, refreshing the hot summer garden with deep, cool purple blooms. Darkest Night ® butterfly bush blooms from summer to frost, providing ample food to butterflies and other pollinators.
