Beautiful Purple Blooms Invite All Kinds of Pollinators to Your Garden!

The Buddleia davidii Black Knight Butterfly Bush is a sight for the eyes planted in any butterfly garden landscape! As long as you have a sunny planting spot this flowering perennial shrub will flourish with big purple flower heads whose fragrance will attract butterflies and other pollinators like bees or hummingbirds to your landscape.

This flowering butterfly bush plant features very dark purple conical flower heads that have a bloom time from early to mid-summer to early fall at their prime. You can start seeing the clusters of flowers as early as May or June and they will last all the way until September. They will appear on a long shrub-like spike that surrounds the circumference of the plant.

Contrasting the deep purple flower spikes on the butterfly weed is olive green foliage that will remain on the plant until winter before dying back. It is famous for its bushy growing habit, honey-scented fragrant flowers, and robust growth. The fast growth rate is perfect for shrub borders, foundation plantings, or specimen plant.

BLACK KNIGHT BUTTERFLY BUSH CARE

The purple Butterfly Bush size is up to 6-8 feet tall and 3-5 feet wide at full maturity. It will perform best in full sun and well-draining soil. It can tolerate partial sun to partial shade but foliage may become infrequent.

Grow the Buddleia Black Knight Butterfly Bush across the United States in USDA hardiness zones 5-9. In northern climate zones like 5 and 6 with colder winters, the deciduous shrub can die down to the ground in winter months in the manner of an herbaceous perennial. Do not fret – the cold-hardy root systems will stay intact and flush out in early spring. Plus, they’re deer resistant

Butterfly bush pruning will benefit the plant after the flowering period ends to help shape the shrub to your desired size. The green leaves can take heavy pruning. Do not prune once spring has arrived to avoid cutting off new flower buds. The best time of the year to prune is in winter.

You can even prune your plant into a butterfly bush tree! Deadhead butterfly bush and remove spent flower blossoms to encourage repeat blooms.

The flowering shrub is rabbit resistant and tolerant of clay soils once established. It is extremely low maintenance and drought tolerant. Once planted you can set it and forget it besides the occasional watering.

Shop the Black Knight Butterfly Bush for sale if you are looking for a purple bush that attracts butterflies and is easy to care for.

Plant the butterfly-attracting bush somewhere the fragrance can be enjoyed!

I ordered this for my cousin, she lost her 19 year old daughter in a tragic car accident. I wanted her yard to be filled with butterflies!

Oh, my heart goes out to your cousin, my friend. Losing a loved one is never easy, and my deepest sympathies go to her during this difficult time. It's incredibly thoughtful of you to want to fill her yard with butterflies, like little winged messengers bringing comfort and a sense of peace.

Perfect indeed...

It came today and is in the ground enjoying the light rain. Lovely young plant and it is happily next to two other butterfly bushes. Black knight is their favorite so I'm hopeful we'll have some monarchs soon.

Good customer service

I had an interesting introduction to this company. The first delivery I received was in perfect condition, even though it was shipped during the start of a heat wave. But it was the wrong plant, and it’s not suitable for my zone. They were great about replacing it with the correct plants. This time, the plants arrived looking very stressed, as the heat wave had escalated to record breaking temps all through the states they had to travel to get to me. I put them in my grow tent and they are slowly putting on new leaves. So, the first shipment I think shows the care they take with shipping. The second shipment shows what a heat dome can to do plants. I would use this company again.

Hey there, Thank you for taking the time to share your experience with us. We're so glad to hear that your first delivery arrived in perfect condition and that we were able to quickly and easily resolve the mix-up with the wrong plant species. As you mentioned, unfortunately, the second delivery coincided with a heat wave, which can certainly be stressful and challenging for plants during shipping. However, it sounds like your plants are resilient and adjusting well in their new grow tent home, which is great news! Thanks for choosing us and we hope to support your gardening endeavors in the future. Happy planting, Shirley
