I would whole heartily agree with the above evaluation of this rose. Its beauty is indeed ethereal and as fine as any of the OGRs. That is the important point. However, I might pedantically quibble with the term 'spiral' for its petal formation. I think of spiral as the form of the typical modern hybrid tea. La Duchesse, like most OGR's, has an imbricated or kaleidoscope pattern of petals.
