I have had this standard David Austin rose for many years but lost the tag soon after I bought it.
I've always thought it might be Graham Thomas.
but someone recently suggested Teasing Georgia or Grace. It looks like some of the photos but isn't as yellow as many of them.
It starts with a pale pinkish colour and a yellowish centre then explodes into this pale yellow star!
I'm in Australia so the candidates might be more limited and it might have a slightly different habit.

Any ideas very welcome.
