That was so helpful, Happypaphy7. Thanks so much. If you hadn't told me, I'm sure I would have assumed something was wrong.
As an aside, I love this little plant. I bought it "blooming size" a couple of years ago. That was incorrect (as I can see now from the size of the leaves that it's producing compared to those when it arrived), but it has been such a tolerant, well-behaved grower, and it's so cute even out of bloom. Of course I wanted it to bloom - a micranthum flower is one of my personal benchmarks and I'm delighted. But I would have kept it "forever", flower or not.
The really neat thing is that I didn't do anything special. No winter cooling, no (intentional) reduction of water. LED lights have been a great equalizer for me, especially re: paphs. Thanks again.
