All-Natural Butterfly and Hummingbird Feeder

Why Black Knight Butterfly Bushes?

Aptly named, the Black Knight Butterfly Bush attracts butterflies like no other plant. Plus, it boasts a luxuriously long blooming period, with the extra perk of drought tolerance for easy upkeep.

Bright, fragrant blooms draw in butterflies and hummingbirds. Plant the butterfly bush in groupings or in rows for a summer-long spectacular show. And this deciduous shrub highlights any garden. The large, elongated clusters of blooms provide ample nectar for all varieties of butterflies and hummingbirds.

A profusion of flowers from mid-July until the first frost reward you month after month with uninterrupted blooming. In fact, our well-developed, 3-gallon container plant will reach its mature height the first year.

Black Knight Butterfly Bush

I am very happy now, it has finally blossoming at this time & just now coming to life! When it first arrived, it was very small & one branch was too heavy & drooped down on that branch. . . . after blooming the first time! Now it's stronger & blooming in the right way! It's developing & will be growing!

This is my second of this bush. First one is blooming and coming along beautifully! Hoping the same from the second. Purchased several different plants and all but one are thriving!

Arrived Alive and Well

Waiting for it to grow. Repotted it until it gets a bit more mature. We have deer and I need to put something around it to protect it until such time. Overall pleased and it came healthy. Not very wilted.
