What is this bush/tree?

[FlowerPig]

Can anyone help me name the below bush/tree?
Wanting to look it up online.... I cut it back last year hoping it'd stay a bit smaller but it grew back twice the size this year (have just removed some branches from the bottom).
Thinking I should have just left it!!
MIL planted it and gave me an orange variation to plant this summer which is growing quickly too so want to be a bit more clues up for next year.

Looks like Buddleia

Yep, buddleia.
They grow like absolute buggers, so cut them back almost completely every year, once the flowers are coming to an end, as they seed ridiculously too. But the flowers are pretty and are loved by butterflies and bees.
In my experience you can't be too harsh with buddleia. And they do look a bit shit for most of the year, if they grow too big.

Yes - it's Buddleia, also known as 'butterfly bush' because it attracts butterflys! Never seen an orange one though - are you sure it's the same plant?

If it does seed and grow weed asap, they will get everywhere all growing to same size and will grow in walls, gutters etc and do damage. I killed my daughter's, quite proud as almost impossible to do!

The most common one that grows like a weed everywhere has the purple flower spikes, but I have also seen the 'orange ball' one in gardens, which I think is attractive, and a white flowered one too.

Thank you all so much, will have a little read up and cut it right back and hope for better next year. It's looked really messy this year but I didn't cut it right back last year, I was too worried about killing it off but will go all in!!

Pictures below of the orange one I planted in May, can't believe how fast it's growing....MIL doesn't actually know the name so it may well be something different, she just took a cutting from her neighbours as she said it was lovely when it flowered.

That's a Buddleia as well. Should be beautiful. I'm going to see if I can find an orange one myself!

I have two orange, two purple and two white buddleias. Or Fucking Buddleias to give them their full name. The one in the front garden has grown 4 feet since I hacked it back last year. I prune it as hard as possible and it goes nuts every year.

Great for bees and butterflies but my goodness, they are RAMPANT.

Orange buddleia is probably going to turn out to be buddleia globosa I think. Which means round clusters of flowers rather than long ones.

I usually deadhead and thin and prune now as well as pruning more at the back end of the year.
I love the smell, and so do the butterflies, it seems.

MIL was right, the orange one is beautiful! I will
Look forward to that flowering next year.
I read online to cut right back to 45cm above ground, that will take me back to the thick wood stumps, is that right?

TBH you could take a flamethrower to most buddleia and it'd shrug its shoulders and come back. Look how it thrives on old buildings!

Every year I cut my buddleia back to knee height. Every year it gets huge. I think this year it has surpassed itself, and is about ten feet tall.

The orange one is lovely! Yes to a flamethrower though. We had a huge one when we moved in, this bloke cut it back and actually put a poison into the remains of the trunk, and it was back two years later

I was absent all last year, and therefore the buddleia went unpruned. It has grown a proper tree trunk and is about 15ft tall. I don't even know how I'm going to tackle the pruning, tbh. A flamethrower might be needed!

That said, it is incredible watching the birds, bees and bumblebees it attacts. There have been lots of visits by peacock butterflies, red admirals and bumblebees. I'm in love.

Good job I quite like it when it's looking tidy, sounds like they're hard to get rid of! Can't believe how they grow on buildings, glad they aren't anywhere near the house for seed spread.

I have hacked it back considerably, most of the flowers were dead anyway and I was sick of the sight of it and it getting in the way of the washing line which we moved earlier this year....which I'm now thinking we'll be better moving again than try and control the bush!!

Tried to get through the thick trunk on the right with a saw but at 7 months pregnant I'm hot, tired and will add it to DPs list of things to (never) do!!

AS well as the orange Buddleia globosa, there's been a bit of hybridisation of B globosa and B davidii (the usual species) to produce Buddleia x wyeriana, which has flowers in apricot rather than glaring orange. The flowers are in balls, like B. globosa, but the balls can be arranged into a conical inforescence the shape of the usual B davidii inflorescence. It's a very lovely thing.

You can see orange is available in the Buddleia colour palette - the centre of the flowers (probably not the white one, which may lack all pigment) is bright orange.

We have an orange buddleia in our front garden. It is an absolute menace. The orange balls look lovely for around 2 possibly 3 weeks and after that it looks dreadful. It has spread sideways and pushed over our bay tree and the branches stretched the entire width of our garden. Okay so I should have realised that I needed to keep well on top of it. It became so thick and woody and I have spent the last 2 years hacking away at it and now it is almost down to several stumps. I want it gone. Pretty when buds out but really not worth the hassle unless you have the time and patience to really, really cut it back frequently. Bear in mind that every single shoot that comes off the branches (even branches that have been cut off) will grow in to a big thick branch. I may now have to pay someone to really demolish it.
