i looks a bit like hypericum did it have yellow flowers..

Thanks for your reply No they are white and grow a bit like lilac blossoms

Could be a spirea arguta (Bridal Wreath).

Thanks Digginfit Dont think so the stems are bright red Does this help?

The only other one I can think of is Deutzia except that the leaves don't look quite right for that. In any case, it would probably benefit from a bit of a prune about now if it's spring flowering. I would take the flowered stems down by about a third and prune out any very old stems from the bottom - as you would a philadelphus. Hope this helps and doesn't hinder!

Can anyone else offer a suggestion as I have googled the above and none seem to quite fit?

Its Spiraea nipponica, probably the form 'Snowmound'

Thanks Fractal that looks about right although mine doesnt seem to have as many flowers as the ones I have googled My fault I presume as I do not know how to care for it properly

All that new growth in the picture will flower all along its length next spring so don't prune it. Only prune immediately after flowers have finished.

Thanks Fractal thats brill Think I must have been pruning at the wrong time in the past Looking forward to seeing it next Spring ! Cheers !
