Any idea what plant this is?

Thank you NantheWiser and Culag. I see what you mean, they look very similar.......

I agree with NanTheWiser.

It's Deutzia, not Philadelphus. Very similar, and easily confused with Phikadelphus, it should have a nice perfume, too.

Ok ladies, so the story goes like this..... daughter bought three plants in Poundland about four years’ ago. Two didn’t survive but this one is doing very well as you can see! She couldn’t remember the name until you all so kindly helped out today! Thanks again!

Wow thank you all! Yes it looks does like a Philadelphus. I will ask daughter if it has a scent and come back you ?

I agree Philadelphus

Mine nowhere near so far on!

It’s a type of Philadelphus, it should have a lovely scent, especially in the evening.

No idea, but it is pretty.
The stems look quite woody so it's probably a shrub, small bush.
Does it have perfume?
