I have a climbing rose in the garden, which is yellow and red (either a climbing version of "Masquerade" or "Joseph's Coat" I suspect) and it occasionally flowers in the middle of winter. The flowers are not full flowers, but are delightful. The petals are small (about the size of a dog rose) are pale lemon/cream in colour, there are about five petals in total, and they don't appear to have the full central reproductive elements. They stay on the bush for much longer than the roses in summer do, but are much fewer, just the odd one here and there. Each summer the normal roses return in abundance, without any sign of the strange winter flowers.
I've three questions if anyone can help. First, obviously, does anyone else see these on the same, or on other species of rose? Second, does anyone know why they occur? Thirdly, and most importantly, will they still appear if I propagate them by cuttings, or is it something to do with their location and climate that wouldn't happen in a different place? I'd love to send my Mother one that does the same thing.
