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.

Awesome experience, Beautiful plants!

I had a very good experience with my first order, two Black Knight Butterfly Bushes. I received my order very quickly, and one was perfect and beautiful. The other had some of the soil spill out of the pot, which exposed some of the roots. I thought if I planted them both as soon as possible, then the one with the exposed roots would come around. Unfortunately, that bush didn’t perish, but, I contacted Fast Growing Trees and used the guarantee that came with my order, and they sent me a beautiful replacement bush, pretty quickly. I planted it and now I have two beautiful Black Knight Butterfly Bushes, which have already caught the attention of the butterflies and bees. And when they’re a bit get a bit taller, the hummingbirds are sure to join the feeding frenzy. Thank you Fast Growing Trees for your quick response and replacement. I have already placed a second order, which I’m eagerly awaiting, and I will definitely recommend you to all of my plant loving friends!

Going well so far

Recover item in good condition. Much smaller than what I expected. It sat on my patio for a few weeks before I planted it. I’m in zone 5. I planted it the first week of June. It is now mid august and it thriving. I recently just had a burst of blooms. And it’s about 3 times bigger than it started.
