Black Knight Butterfly Bush - Graceful trusses smothered with dark purple flowers from midsummer to fall attract flocks of butterflies. 6-8' tall with a similar spread. Ships in a 4" pot. Zones 4-9 Buddleia davidii ‘Black Knight’...the photo does not do this beautiful plant justice...dark almost black flowerettes with hearts of bright magenta.
With this drought-tolerant garden bed, all of the plants can withstand drier conditions -- although naturally they’ll look fuller and more vigorous with ample moisture. Description from lowes.com. I searched for this on bing.com/images
