It is certainly an escallonia, and it looks quite like Apple Blossom. There are lots of different varieties - perhaps someone else will be able to give a definite answer.

its too dark for apple blossom, well compared to mine it is. There are several named ones but I cant help with this one.

I did wonder about Apple Blossom, but agree probably too dark. I've been googling images but can't find one that looks like this.

Could be apple or peach blossom but will differ in colour depending on the age of the flowers as they will probably lighten with age.

I think it's too dark for apple blossom too.Mine was much paler..There is one in my book,called 'Glory of Donard' which says it is a pink one,but no picture..maybe try that one..?good luck..

i reckon its Escallonia Pride of Donard

I wonder if this is the same one,with a different name,Bamboo ? my book is one of the older Dr D.G. Hessayon books,'Trees and shrubs',dated 1983 !

No, Bloomer, there are an awful lot of 'Donard' escallonias - Donard Seedling, Donard Radiance, Donard Beauty, Donard Brilliance, Pride of Donard and Slieve Donard... that Donard bloke's been really, really busy...

Well,I'll be blowed ! you learn something every day,or at least I seem to do..thanks for that info,Bamboo..

See new photos and idea above in original question, which I've updated.

Thanks for all the help - hopefully we'll get there between us!

Next question - can I take cuttings to create new shrubs from this? If so, what do I do?

Well the second picture certainly looks like Donard Seedling. Propagation is by semi ripe cuttings now.

Yes the second picture is Donard Seedling - but is the first one?

I don't know what you mean by semi ripe cuttings, sorry! I need an idiot's guide.

It means cuttings of parts that aren't all soft and floppy, really sappy, but not yet hard and firm. Google semi ripe cuttings, there should be online guides and possibly demonstrations.

Thank you Bamboo, I'll do that.
