Vermilion Zygo

Day 57: I always seem to neglect the common colors of Zygocactus in my collection in favor of the more showy and unusual varieties, but they are equally rewarding and a welcome sight in the grey months of November and December. This is one I describe as "vermilion," as opposed to the other mundane "cerise" species on the shelf (not currently fully open). Some varieties are natural mutations; others have been carefully engineered genetically, however, all have the same hot-pink stigma and a roughly-drawn pencil-line of the same color marks the white interior of the flower as if to remind us that the hereditary stock of all Christmas cacti was indeed a deep, rich pink (a color I can forgive in Nature, but nowhere else).
