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.

Black Knight B-Fly Tre
Great! It arrived in super shape and we planted it immediately. It is super happy in its new location and has new blooms and butterflies swarming all over it!!!
Black Night Butterfly Bush damaged/ but replaced
The plant arrived broken due to shipping. Fast Growing trees replaced and made it right. I ended up planting anyway and it appears to have come out of the damage. I've bought darn near every butterfly plant that they have available, and they are all doing well. Two thumbs all the way up. I couldn't be happier. The butterfly's and hummingbirds love em!
good packing
got to see how it turns out - thin stem. Pic in the website a little misleading. Happy to know it will turn out like that but would also like to see how it looks when we get it
Cont. . . Just received today and planted
Since I can't update my original review with an updated picture I had to write a new one. . . My bushes are thriving, creating new buds, and are blooming (Zone 8b). These were planted May 02, 2025 so roughly 10 days after receiving the Butterfly Bush.
Just received today and planted
Just delivered other than a few broken branches it looks great. Planted during a rainstorm.
