might be a leucothe but cant say for certain.

Thank you. I'll look that up. I'll try to take some more photos when the flowers come out.

Alternatively, compare it to Photinia 'Pink Marble', although if you've had it longer than 5 years that won't be it.

I agree with Teadrinker but instead of Pink Marble, might it be Pallete?

Thank you. I'll look up both of those.

I think you have ID'd my plant too Scottish. You grew the one you gave me from a cutting from a neighbours garden. It is flowering just like this and the RHS description of flat heads of white flowers fits too. When you gave it to me you thought it might be Pink Marble but I have since received one of them and it is similar but different.

Scotsgran, I thought I had mentioned about it possibly being Pallete, maybe I forgot, I seem to be doing a lot of that lately. I'm getting old...lol!! :)

You and me both Scottish. Great excuse though if not over used.
