Buddleia davidii ‘Black Knight’

Butterfly Bush

USDA Zone: 5-9

Plant number: 1.106.750

The fragrant, arching clusters of Butterfly Bush are irresistible to hummingbirds and butterflies. Really a shrub, plants are best treated like perennials and pruned back hard each spring, to maintain a compact, bushy habit. This selection has long wands of dark purple flowers, on a tall clump. Excellent for cutting. Removing faded flower heads will encourage plants to continue blooming. Drought and heat tolerant once established.
