Great thread! I was just about to post the same one! I have the same plant and want to see if I can put it outside.
It's an amazingly resilient little bugger, I killed it and was going to compost it in the spring when all of a sudden it started blooming again over the winter.
I had sought high and low for the answer for weeks now, withing five minutes of posting my inquiry I found the answer by accident.
Well Im glad you did! Thanks! Now I can try to figure out how to deal with mine....its some ugly lately.
From what I gather they are winter bloomers so it is most likely at the end of its reproductive stage. Whatever you do don't over water it, in fact I hadn't watered mine in months when I noticed the foliage start to show in October. I thought it was dead and all of a sudden it bloomed out of nowhere.
Looks like one of the original Kalanchoe blossfeldiana cultivars and not one of those super multispecies hybrids now often seen passing for it in the trade. It originates from northern Madagascar and is not at all cold hardy.
