This pink cactus is actually a Spring-blooming "Easter Cactus" but it's got a few blooms right now. And since we've got lots of Christmas Cactus blooms right now, I figured it would be fun to try some crossing. I marked the ones I pollinated, with a black dot (Sharpie marker), so I'll know if it's worked. So far all unmarked blooms have dropped off along with the tiny fruits when they've closed. One of the marked ones is still holding on, even after closing.
This coral- colored Christmas Cactus is the pollen I used.
