Pretty in blue Echeveria

I bought this little guy about three years ago at a local florist shop. I also bought several other plants, a couple of Haworthia and some others. My plan was to group them in a shallow dish, which looked really nice. I did that for about two years, and got lots of comments about it when guests would see it at the front step.
I'm not even sure that this is an Echeveria, but I can't find any information about it anywhere. It gets a bit leggy, and then if I pinch out the long parts, it branches out all over. It doesn't seem to make a rosette, except at the top of each stem. It has never flowered for me. My one complaint about it is that it seems to drop leaves whenever you look at it, and then they all root too! I'd love to find out what it is!
