Twice-Blooming Christmas Cacti?

I have a lovely pair of Schlumbergera. They used to live on the windowsill in my bathroom, where they gave me pretty, bright white blooms with hot pink pistils every winter. I looked forward to seeing them every year — individually, the flowers themselves don’t last very long (only about a week per bloom), so it was a little window of beauty in the middle of the cold, gray winter season.

Schlumbergera bridgesii are better known as Christmas cacti, and for good reason — they flower in December. It’s always exciting, watching the little buds pop out of the end of the flat, spiky-edged leaves, growing and lengthening until the flowers finally burst forth. December rolls around, everything else is in the midst of dormancy, but these cacti happily put out flowers anyhow.

Yep.

Every December.

You know, when Christmas happens.

If you notice the leaves don’t really resemble the smooth, round leaves of other Christmas cacti, that’s because holiday cacti nomenclature and labeling makes no sense. This one was labeled as S. bridgesii, which is actually S. buckleyi, and doesn’t look anything like most other S. buckleyi cultivars I’ve seen. ¯\_(ツ)_/¯

So, someone tell me what’s up with this nerd. 

See, not long ago, I moved both of my plants into a warmer, brighter window, on the top shelf of my new plant shelves. Now, I’m not sure what triggers S. bridgesii to flower, exactly — shortening daylight hours? Cooler weather? I don’t know. There are ways to force it into dormancy and trigger flowering, but I didn’t do anything out of the ordinary before moving it. I didn’t even restrict light or water.

I’m not complaining, of course — this little plant’s putting out more flowers now than it did two months ago. It looks healthy and vibrant. The cactus right next to it doesn’t have a single bud on it, but it’s also not really supposed to.

Is it possible for S. bridgesii to flower late, if it didn’t flower during Christmas? I’d say so. Is it possible for one to flower more than once a year? Apparently! Unfortunately, I don’t know exactly what triggered this one to start putting out blooms now, but I’m going to keep an eye on both of them and see if the other decides to put out more buds. Maybe take a few cuttings and try some experiments.
