Hi sleepingbeard, with echeverias, oftentimes, they will do that, grow taller, dropping the older leaves and then it exposes a long neck, similar to what Aeoniums do. Now you can do as Patti suggested, cutting off the top growing half, and let it root. Or you can keep it growing tall and it may or may not grow new rosettes up and down the stem. But it varies. I do not know really what triggers it to do the new rosettes along the stems, sometimes they do or sometimes it is just at the base of the plant. Then it may go top heavy and lean forward as it goes. It looks sad when it does it, but to me as long as the stems are holding firm, it is okay. But if I get tired looking at it appearing sad, I cut off that top growing part and set aside to root. It does take longer to root when it is into cooler weather, but it will, just give it time. So if you can wait, wait to do the chopping part when it is Spring, so warmer conditions are longer. Just try to keep it dry this winter. It can take some coolness maybe up to 40F but have to keep it really dry. To play safe, keep it indoors by your south facing window and dry, that should make it easier
This is my echeveria elegans before: June 2013
Photo last April 2015 - very long neck, and there is a new rosette down the stem, but not quite at the base of the plant
These were some of the echeveria elegans I have cut off in Jan 2015, just to experiment the rooting aspect, keeping them dry indoors in part shade area, trying to see where exactly does the roots appear: so roots appear anywhere above the callused area.
