Christmas Cactus Flower Blooming in March & April

I don't know if this is a Climate Change issue or what. Last winter our Christmas cactus bloomed and bloomed through the later part of December through much of January. This winter it bloomed off and on during that same period, and then it started blooming quite more the last half of March and into April.

The flowers look so fragile I'm afraid they'll fall right off if disturbed. One of them was standing out so nicely it was easy to set my tripod with iPhone and Moment wide lens up close without disturbing the plant.

The face of the wide lens was about 2-3 cm from the flower. CameraPixels was used to focus bracket 40 images, and Affinity Photo was used to focus align and merge the images.
