I still have reservations that my rose is in fact 'Blanchefleur'. It seems to me to be a suckering upright-caned gallica with no arching centifolia traits.
Museo Giardino della Rosa Antica in Italy and Flor in Germany show photos of hips. I have noted in my files that my Blanchfleur sets no hips but have made a diary note to double check in early 2024 for any hip set. I see from my 2010 photo that my Blanchfleur appear to have female carpels and no male stamens (unless the carpels and stamens are of the same height?).
If any member has photos of the bush habit and/or hips, they would be appreciated.

In my very moist garden is subject to rust

I planted this rose as a band in my garden last year, and I am blown away by how much it's grown and by how many flowers it has produced in its first spring. It's a truly gorgeous rose and one of my new favorites in my Zone 6b CT garden. Highly recommended!
