Which buddleia is sterile




















It is called Flutterbye bush. Check it out online. I ordered two Buddleia davidii 'Black Knight' plants that will arrive in May. I would think that dead heading the fading flower heads before they go to seed would not only promote more flowers but also prevent the plant from being invasive.

I guess I'll find out for sure this summer. I never knew you could prune Buddleia davidii intom a tree: very interesting. But I have seen another selection presumed to be from different crossing of same species reseed. I would be wary of anything with B. As soon as it is discontinued, if the specimen remains present beyond this point then it will be able to seed out anywhere there is suitable conditions.

Here barren places such as margins of parking lots, river banks and even the stone faces of older buildings sprout numbers of them. I didn't realize they were so invasive. Well, I'm only planting two of them, so it shouldn't be that hard to keep up I am planting them right next to some Miss Huff Lantanas. I also have Pink caprice Lantanas, Blanket Flowers, and Purple Cone Flowers within the vicinity, so all of that should keep the butterflies and hummers happy this summer.

This is what B davidii will do where it is happy. Picture taken November down the road from my place. As bboy said - it loves stony places including walls. The seeds are prolific and wind borne, so unless you can remove every spent flower before it ripens some will get away.

Someone needs to alert the building engineer of the problem. Worst infestations here are probably those around rivers, where it forms thickets. If there is no surface water it even grows in the river bed, as well as on gravel bars etc.

A river runs right through the middle of the town I live in. Due to the extended drought, it is more like a creek than a river, and there are shrubs and trees growing all over it now. I don't know if any of the shrubs are butterfly bushes though.

The river is about a mile from where I live. I do have quite a bit of barren ground in my backyard, which I am going to sprig it with Bermuda grass this summer.

Hopefully, the Bermuda will help keep any Buddliea seeds from getting down into the soil if I lose the handle on deadheading them. If not, then I'm sure the lawnmower will make short work of them. I wouldn't expect it to come up very often in grass or anywhere else a substantial growth of other plants was already present. Here it seems to be pretty consistent about appearing in bare places, often where there are rocks present to some degree.

It's probably the same situation as with desert cacti, in that the young seedlings survive the harshness of the site by sheltering among rocks.

Those few places I have seen empress trees coming up from seed here were also always rocky - usually, in fact, stone walls or borders - except for a quite moist yet exposed patch of automatically irrigated flower bed across the street.

The summer drought here is quite an inhibitor for any plants not adapted to it or able to get into places where it is ameliorated enough for them get by until fall. Well, it doesn't sound like I have much to be concerned about with Buddleia davidii popping up all over the neighborhood.

I do enjoy dead heading, so I really don't think I will have an issue even if I were surrounded by rivers and stone walls. Here is also widespread along railway tracks, in disused sidings, etc. It loves the ballast, just as bboy says. I have had butterfly bushes for 16 years here central Alabama. In that time, I have had two come up from seed. I am not a reliable at dead-heading.

I currently have 4 of them and love them. It is hot and humid here, and I have clay soil. One of the things about Buddleja's invasiveness is that it does not necessarily self sow near the parent. The seeds are wind born and can travel miles before settling in a conducive spot. I have a lot coming up in my wood a long way from any gardens. I do drive by one frequently that came up in grass, but it is beneath a chain link fence right on the edge of the lawn, in a rough strip where the mower doesn't reach.

There are probably gaps in that part that made it possible for the shrub to take hold. The same section of fence also has broom Cytisus scoparius and I think blackberry Rubus armeniacus growing through it. PLant native!!! OK so maybe a couple of non native And planting native can be hard.. I've been trying and will keep trying. Update: My Buddleia davidii has since been shovel pruned.

I kept getting severe ifestations of Two Spotted Spider Mites. I tried to control them with a jet of water, but that didn't work. I tried to control them with foliar insecticide, but that didn't work either.

The second year was more of the same, but the spider mites began to spread to other plants in my yard. Spider mites can be controlled with a commercial miticide or oil spray, but it is better to keep the plant stress free by providing adequate moisture, soil drainage, and fertilizer.

It is best to minimize chemicals, especially if your goal is to provide a breeding ground for butterflies. Buddleia are considered to be deer resistant. Deer prefer many other plants and will only feed on the butterfly bush as a last resort. The sweetly scented Buddleia flowers attract many types of butterflies and at times, the flowers will be covered with hundreds of them.

Butterfly bush flowers serve as a nectar source for adult butterflies and the leaves too feed the larvae of some butterfly species. Buddleia are host plants to the North American butterfly species listed below: Buddleia 'Summer Beauty'. Bees, wasps, hornets, lady beetles, lacewings and moths also enjoy the flowers. Hummingbirds are attracted by the reddish cultivars. Other birds such as orioles and bushtits will feed on the nectar during the growing season and on the seeds in winter.

Today, there are dozens of Buddleia cultivars on the market. Plant Delights Nursery is proud to have been the first to release two cultivars Buddleia 'Orange Scepter' , and Buddleia davidii 'Potter's Purple' We strive to grow only the most interesting and evocative specimens, as well as some of the newest plants on the market.

Buddleia 'Attraction' is toward the red-purple spectrum and a dramatic improvement over Buddleia 'Royal Red'. This is a tremendous breakthrough in butterfly bush breeding, and who knows?

Gardeners who want to attract butterflies to their gardens often plant butterfly bush genus Buddleia , a fast growing shrub that blooms prolifically. While butterfly bush is easy to grow, inexpensive to buy, and a good attractant for butterflies, some argue it's one of the worst choices for a butterfly garden.

For years, butterfly bush Buddleia has divided gardeners into two camps: those who plant it without apology, and those who think it should be banned.

Fortunately, it's now possible to plant butterfly bushes without negatively impacting the environment. Buddleia is well-loved by butterfly gardeners because it is well-loved by butterflies. It blooms from spring to fall depending on your growing zone , and produces an abundance of nectar-rich flowers that butterflies cannot resist. Butterfly bush is easy-to-grow and tolerates poor soil conditions.

It requires almost no maintenance, other than an annual hard pruning and some gardeners even skip that. Unfortunately, a plant that produces such a bumper crop of flowers also produces a bumper crop of seeds. Buddleia is not native to North America; butterfly bush is an exotic plant from Asia. Ecologists deemed the shrub a threat to native ecosystems, as butterfly bush seeds escaped backyard gardens and invaded forests and meadows. Some states banned the sale of Buddleia and listed it as a noxious, invasive weed.

For commercial growers and nurseries, these bans were consequential. Despite Buddleia 's environmental impact, gardeners still wanted their butterfly bushes, and growers wanted to continue producing and selling it. Butterfly bush has been declared invasive in many regions including much of the Pacific Northwest, parts of coastal California and along the eastern seaboard. There are regions where the threat of invasive spreading is lower due to climate or availability, but some gardeners still choose to steer clear.

If you live in one of the invasive areas and already grow butterfly bush, your best course of action is to dig up your plant and replace it with one of the sterile types shown above. However, if you deadhead butterfly bush meticulously before it goes to seed you may be able to halt the spread.
