Festive Season Flower Limelight Dancer
This is a hybrid in the part of Schlumbergera with teeth on the edges and ends of joints. These are the old genus Zygocactus.
This is one with a lot of yellow. Many years ago, it was rumoured that the first yellow ones were obtained by exposure to nuclear radiation in a reactor. That was probably to throw would-be breeders of the scent. I have a tiny species which has yellow flowers and has been used for breeding.
I was disappointed with the colour until I viewed the flowers in daylight. Indoor tungsten lighting tends to wipe out the yellow. These were, therefore, photographed in weak sunlight.
The intensity of the colour varies with the ambient temperature and darkens if the buds develop at under 15 C.
