A garden classic since 1959, ‘Black Knight’ butterfly bush boasts some of the most dramatically colored flowers you’ll find in a butterfly bush. They aren’t quite black, but they are an intriguing deep purple-blue that few other plants can match. This butterfly bush looks fantastic paired with bright pinks, crisp whites, and cheery yellows. Deadheading is recommended for this old-fashioned variety to encourage continued flower production.
‘Black Knight’ received the prestigious Award of Garden Merit from the Royal Horticultural Society (RHS) in 1993. Cannot be shipped to OR or WA.
