can anyone identify this rose variety please

To my knowledge, there is no rose, wild or otherwise, that has this kind of flower, the closest would be a frilled edge, like Grootendorst. Are you certain the flowers in the picture were actually growing off the stem of the rose - they certainly look as if they are from the picture. When you say "the rest is like a dog rose", do you mean other flowers, or are you referring to the leaves and stems?

The flower is on what looks like the leaves and stem of a dog rose.I've never seen anything like this before. The petals of the flower look exactly like feathers, I wish I'd taken some better pictures too.

Pity you didn't take a lump or a cutting - if those really are the flowers, it might be worth a mint!

I am able to take a cutting. I was thinking exactly that myself. (-:

the reddish mass is a plant gall commonly called a 'robins pincushion'. it is a response to an insect pest, cant remember which one.
next season it wont even be there.

so sorry not a new rose flower at all.

Diplolepis rosea a parasitic wasp according to hubby. the grubs cause the plant wound response.

Thank you very much for your responses.

Oh, how disappointing:-(
