Dear Historische Rosenschätze,

I would like to contact you to know if you can give me some advice on my unknown rose. Do you know if my unknown rose (see picture attached) could be 'Admiral Dewey', the white sport of 'Madame Caroline Testout'? I have been trying to ID this rose for more than 5 years with no success and I saw you are one of the suppliers of this old HT.

Thanks in advance for your kind help and my warmest greetings from Argentina,
Mariano
