I'm wondering whether 'Mme. Charles' might be a possibility for the real identity of 'Miss Atwood'. Both are large bushes, virtually thornless and somewhat Safranoesque in flower shape and colour.
Thank you very much. This is a possibility, need to check the references and the plant more closely. I have moved the picture to 'Souv. de Gabrielle Drevet', but made a note to 'Miss Atwood'.
Yes, while the blooms are similar, those of Miss Atwood are lighter in colour, aging from yellwoish pink to cream; while Dr. Grill has stronger orange-apricot tones. Its buds are also deeper pink. Colour range and form of foliage is similar, equally the stipules. Both have small, sharp, hooked prickles on the underside of rachis. The really evident difference in our plants are the prickles on Dr. Grill's canes.
