Rhipsalidopsis is supposed to bloom in the spring, and hasn't bloomed in the six years I've had, except when I brought it home from the store.
It was growing too long on one side so I gave it a "haircut", and planted several of the segments I removed. Hopefully I will have lots of these plants to share with patient people who might get them to bloom. (They need a period of cold when the temperature goes down into the 50's at night.) It went into the 40's last night, so I brought it inside.)
