This has been a terrific rose for me in Zone 5. It sets beautiful hips, great fall color, nice single flowers with great fragrance. It bloomed for over 8 weeks before stopping. Something I have not seen mentioned anywhere--the canes are a brilliant red in winter, very much like the redtwig dogwood I also have. Don't know if this is typical for this rose, but thought I'd mention it.
Thank you for posting your observations of this rose. I have found that I love seeing the different colored canes of roses in the garden in winter. It's almost like viewing garden art.
