Buddleja, Butterfly Bush, Orange-Eye Butterflybush, Summer Lilac 'Black Knight'

I have 3 of these at my main home and one at the lake house. I love them! They bloom for a long time with minimal deadheading and, if p...Read Moreruned well, do not spread. The butterflies love them, too, and at times are covered with them.
I looked at the neutral and negative responses and think it must be the areas that are causing problems. Here in SW and NC Ohio we do have heat and drought at times, but not prolonged.
I love the dark purple color. Once established they don't need constant watering. I use them as a backdrop or centerpiece for other perennials in layered heights.

Our Black Knight butterfly bush was quite lovely for several years, but succumbed to encroaching shade. We cut it back to about 12" annu...Read Moreally in late winter, and it successfully resprouted to a manageable size, but eventually it did not return for us. The color of the flowers was dramatic, with a fragrance so rich it was almost culinary. Monarch butterflies were regular visitors as were Yellow Swallowtails and Mourning Cloaks. The offspring of this plant bloomed medium purple 90% of the time.

Does not like wet feet, do a raised bed if in a wet clay area. Beautiful with low growing yellow lantana under planted.

LOVE this bush!! It likes at least some water and will pout if it dries out in my sandy-loam soil. My Black Knight grew very quickly to...Read More at least 15 feet, is covered with large (well over a foot) wonderfully scented panicles. I also have this plant in raspberry (beautiful and almost as vigorous), yellow (a more "bushy" shape with smaller, less fragrant flowers), and lavender (after pruning this spring it grew 6 feet in just a few months!). I have 5 acres and if I or my friends want a bush, I just put a branch into the ground and let it get watered with the rest of the flowers. Ignore it if the leaves fall off. By next spring you'll have another bush to share. Black Knight is the easiest of all to root and grows jubilantly right from the start. I have one happy bush in all day dappled sun and another with it's feet in the shade and it's head in full sun. Others are in morning shade /afternoon sun and vice versa. They all seem very happy.

I tried to treat them but couldn't seem to get on top of the problem. After the spider mites began to spread to my Froebelli Spireas, I decided that it was time for the butterfly bushed to go, so I shovel pruned them.

As with most Butterfly Bush, this is a great plant. Nice dark color and that thick scent that fills the air. Brings in the butterflies in droves.

I planted one of these bushes about twenty years ago. I think that one died - but it is hard to tell since I now have about ten of them ...Read More- none which I have planted. They are beautiful in bloom and if you dead head them the flowers just keep on coming. Butterflies, bees, and hummingbirds love them. It is a real treat to watch them from my office window all day as they move between those, crape myrtles, and heptacodium trees. They bloom from mid summer to late fall. They don't seem to die back here, but in the years I forgot to cut them back to about a foot or two the bushes became unruly, huge, and not very attractive. Lesson learned. Remember to cut them back if you want them to remain attractive. They have brittle wood, especially on older plants that will split. I don't know if they propagate from seed or by undergroung runners but they do tend to pop up all over the place, which is good if you decide you want a large shrub to hide something and don't want to go out to the store and buy one. Generally they will sprout up just about everywhere.. I even have another variety which I never planted with smaller flowers that grew up on a south facing hill that I only water occassionally and it is now a large shrub. They are invasive and if you want a plant that does not reproduce all over the place this is not the plant for you. If you don't mind pulling out those you do not want and enjoy the never ending parade of wildlife that these plants attract - then by all means plant it. You will never be without summer color.

I am loving this plant. Never seen so many different butterflies. I deadhead often to ensure it has fresh flowers for them. Yay!!

A similar situation has taken place with new varieties of corn that will not reproduce from the seed. Where are we headed if we try to re-engineer nature? I collect the butterfly seeds and have spread them around my garden. Each year a handful of new plants appear, but they do not appear to be taking over the world. I hope to some day have many more of these bushes and continue to attract more butterflies. This is one of my favorite plants in my garden.

Also, the individual blooms do not last a long time, so regular deadheading cleans up the plant. It is a little slow to get started in the spring, but once it does, it really grows fast! Also, in colder climates (such as where I live in zone 6), cut the plant all the way back to within about 12 inches of the ground in late winter. It may seem drastic but it really does encourage it to come back bigger and better each year. This is the most fragrant plant on our property.

For those who want to attract butterflies this plant takes the cake by far, Black knights flowers are super sweet and irresistable to butterflies,

Butterflies, bees and hummers CANNOT resist this plant. It has an almost overpowering sweet smell. Flower cones are of medium length, not as long as some of the other Buddleja cultivars. It's color is a rich, almost black purple, hence the name, Black Knight.

Plants can be trained to bush out or to grow more upright which lets it fit perfectly into a butterfly garden setting.

If you want butterflies..please plant a Buddlea...I've just counted about 50 butterflies on it!
