My NOID Rhipsalis bloomed at the end of January. The flowers weren't particularly interesting -- especially not by comparison with most cactus flowers -- but it was still something I hadn't seen before.
I don't yet know if they're self-fertile, but it looks like they may be; the flowers (there were two; these pictures are of the first) are no longer open, but the base of the flowers appears to be swelling. I suppose we'll know more in a few months.
Sorry this isn't much; I'd intended to do a different post today and couldn't figure out how to end it, so I threw this post together at the last minute last night.
