Heavy-Blooming and Dramatic Purple Flowers
The Black Knight Butterfly Bush in Tree Form has some of the most intensely purple and prolific flowers that grow in spikes. This tree has dark green foliage and an arching, spreading habit that makes it perfect for borders, beds, and as a privacy screen.
The name doesn’t disappoint, as this plant is a magnet for butterflies and other pollinators. It emits a strong honey-scented fragrance that they just can’t resist and find the flowers rich in nectar. This plant blooms all summer long, giving you a beautiful display of not only flowers but visiting butterflies.
‘Black Knight’ is a pest-resistant variety that is also deer and rabbit-resistant. Butterfly bushes are known for being very easy to grow, needing very little maintenance. This variety is cold hardy, growing in temperatures as low as Zone 4.

Great Plant/Tree
I received this Butterfly Bush Tree by accident. I had ordered a different plant and received this instead. Fast Growing Trees had me keep it and they also sent my original order. This is a $149. 00 tree! It is growing well and arrived well packed. There are no blooms to show yet, but I know they are coming. I’m so thankful for this wonderful, unexpected surprise. Thank you Fast Growing Trees!
