Our Butterfly Bush was packaged well and arrived safely. There were actually three bushes in that pot and I planted one in my 'secret garden,' one in the front yard and gave one to my neighbor. All three have responded well to their new environment and produced beautiful deep purple blooms within a very short time which I enjoyed tremendously. It seems every time I sat down and enjoyed the blooms, I saw at least one butterfly. You weren't kidding! Thank you so much for the wonderful addition to our home

I ordered two of these, one died and the other grew at a fantastic rate. Planted it in late April and it was about 3 ft high in some places by mid-July. Really beautiful and the butterflies practically swarmed it

sun sensitive
made the mistake of putting it where it gets partial sunshine(due to seasonal movement of sun), now growing only one direction to reach the sunlight, but not really the plants' fault! Still attracting butterflies though!!

Beautiful Addition to My Driveway
Ordered three Butterfly bushes early this year and for a while, I was concerned about the health of the plants. I contacted Customer Service who told me to let Nature take its' course and lo' and behold, the bushes are beautiful. It is now July and the flowers on them are just like the magazine shows. The bushes proved to be quite hardy and easy to maintain. I absolutely love them.

I bought one of these last spring and planted it in early June. It grew and had beautiful, beautiful flowers on it! I was looking forward to it blooming again this year, but unfortunately my new lawn service guy cut the bush right to the ground today! I will have to buy another one ASAP to get it in the ground for this season

Planting & Care

It's Easy to Plant & Care for Your Black Knight Butterfly Bush

Step 1: Dig Your Hole

Select a site with full to partial sun and moist or well drained soil for your Black Knight Butterfly Bush.

First, dig each hole so that it is just shallower than the root ball and at least twice the width.

Then loosen the soil in the planting hole so the roots can easily break through.

Use your shovel or try dragging the points of a pitch fork along the sides and bottom of the hole.

Step 2: Place Your Plant

Next, separate the roots of your Black Knight Butterfly Bush gently with your fingers and position them downward in the hole.

The top of the root flare, where the roots end and the trunk begins, should be about an inch above the surrounding soil.

Then make sure the plant is exactly vertical in the hole.

To make it just right, use a level.

Step 3: Backfill Your Hole

As you backfill the hole, apply water to remove air pockets.

Remove debris like stones and grass and completely break up any dirt clumps.

Water your Black Knight Butterfly Bush again after the transplant is complete.

something pretty to attract the butterflies
JUDITH K on Jul 14, 2016
This is to James and wife Danielle from Mary and Jeff Cotter. They just moved into a house about a year ago and have only been married 2 years. Danielle's grandmother passed away and I thought this would be something she can keep for years to come and enjoy in her yard in memory of her grandmother. James and Danielle live in TN and Jeff and I live in NC. Thank you for your help.

I need to know if you trim the Bush at some point & when & how fare down the stem do I go? Also will it come back next year?
Sheila on Aug 27, 2014
Best Answer: You don't have to trim Butterfly Bushes, but since they bloom on new growth, many gardeners prune theirs back every year to encourage more bloom and a smaller bush. In fact, in the northern portion of its range, Buddleia dies back to the ground every winter, achieving the same effect as a heavy pruning. You can cut the stems all the way back to 12 to 24 inches, depending on your personal taste; this should be done in late winter to early spring, but not in fall, for the hollow branches will hold water and split when it freezes.

Do deer bother this bush?
A shopper on Sep 8, 2014
Best Answer: Butterfly Bushes are considered deer resistant, as they do not come high on the list of Deer's Favorite Foods. That being said, a hungry deer will eat most anything, so if your plant is readily accessible and food is scarce, your Black Knight might be nibbled on. The good news is that Buddleia takes pruning well, whether by you or by deer!

Does this take full sun?
A shopper on Jun 7, 2014
Best Answer: I purchased two. One was placed in an area where it had limited sunlight exposure and did very well. The other was placed in a different location with full North Carolina sun all day. It did not do nearly as well. I have had butterfly bushes before that did very well in the sun. Both are now emerging into their second season. Looking forward to how they will respond to their surroundings without the trauma of initial transplantation.

Will it attract Bees?
Paula J on Sep 10, 2015
Best Answer: I haven't seen any bees at that bush but the bees sure like our lavender bush which is close to it. Our buttlerly population has been in decline for the last few years and so has the bee population and that may be why I haven't seen the bees at the bush. Hope this helps you.

How deep and widespread is the root system? Can this be planted next to a home's foundation?
Michelle J on Aug 9, 2015
Best Answer: Hi,
Our butterfly bush is 2 years old and is quite large. We planted it in a border around our patio in full sun and it us very happy. I cannot image this bushlanted cole to a foundation because the canopy is so wide. Better to plant further away from the house so you can see it blooming. The bush arrived in a box and was planted in the fall. Grew well and bloomed first year but really took took off this year. I hope these comments are helpful to your planning.

Do I remove the dead stems after the growing season or leave them to shelter new growth ?
Bette B on May 22, 2015
Best Answer: Yes, cut the whole plant down to about 10" after the winter is over. The entire plant grows back up from the ground. It will be twice as big this year. I love it! Also, if you want more blooms, dead head the died off blooms and new ones will keep forming.

do these bushes come back from the ground or the plant think mine died but are shoots at the base?
sandy w on Jun 15, 2014
Best Answer: If it still has shoots coming from the base, it's not completely dead. I would make sure that the roots are covered and that there are no air pockets around the roots, and give it water. Maybe you could buy some of the special planting mix that Fast Growing Trees? It has lots of nutrients that growing butterfly bushes need.

bought one last year and it didn't come back.
Why would that happen?
Dan M on Jun 25, 2015
Best Answer: In general, Butterfly Bushes are pretty tough and hard to kill. If you have an exceptionally cold winter (like we did this last winter), it can kill not just the stems but the roots, and if you have a longish warm spell in winter that gets sap to stirring, followed by a cold snap, you can lose your Buddleia. Another condition that can do in a Butterfly Bush is having a site that is not well-enough drained, so the roots stay wet in winter; this can kill a Butterfly Bush, also.

Will trees and shrubs look like the photographs?

Most trees and plants on the website are pictured in their mature form. Depending on the product and growth rate, mature development can take years for your plant to resemble the photos. Picture the last time you took a walk in the woods. The young trees were not miniature bonsai versions of mature trees. Instead they were naturally thin and lanky. Young trees are programmed to race toward the light, before the competing vegetation crowds them out. Once established at 10 feet or more, they start developing a wide canopy and shedding lower limbs.

Trimming & Pruning

Most Trees and Shrubs are Pruned Before Shipping... at No Cost to You!

Pruning makes plants appear to be less-full than the ones you may have seen at your local big box garden center. A retailer's goal is to have plants look their best while sitting in the store. Our goal is to have them look the best after you plant them.

Pruned trees and shrubs not only travel better, but become established much quicker. So rather than supporting extra foliage, they put their energy into sending out deep roots. Once that happens, your plants become hardier and quickly explode with new top growth. Above the ground, pruning helps your plants develop a more attractive form.
