Susan,

Smarter people than I am will correct me, but it looks like you have an intragenetic hybrid of Echeveria x Graptopetalum or Echeveria x Pachyphytum - all of these are New World Crassulaceae (NWC, as opposed to the OWC, Old World....., such as your common Crassula ovata, the jade plant) and interbreed promiscuously, to the delight of many.

You're growing it well, as evidenced by the flowers and healthy plant, and the problems you describe can be somewhat ascribed to the type of pot it's in - I'd look for a bulb pot of some type (one that's wider than it is tall) to pot this in, because this is the growth habit of many of these NWC - many of them in their habitats are cliff-dwellers, or nearly so, and want to grow in a spill-over fashion.

Well, thank you! You've given me a lot of help, and ideas for things to read up on :)

It looks something like Pachyveria 'exotica' (Pachyphytum x Echeveria), but Graptoveria or something even more 'in-between' is always possible.

Pot-tipping is always a problem with such top-heavy succulents. The solution is to add ballast stones to the pot. The bigger and more off balance the plant, the heavier the stones. Of course, a prudent beheading once in awhile is always helpful to even things out. Root and pot the decapitated heads. I perform a series of public executions and resurrections this time of year. Try it, it's fun!

Leaf recycling of the oldest leaves is normal, especially in winter when it's 'out with the old, in with the new'. In summer, it can be a sign of underwatering, but as long as it is the oldest leaves dessicating, there is nothing to worry about. I agree with Jeffrey, you are growing it well.

Looks like my x. Sedeveria 'Harry Butterfield'...

Yours looks very healthy to me. I can't give mine quite enough sun in the winter months, so it loses its pink tinge and gets a little leggy in the winter.

Thank you. I keep it in my heated (but not hot) greenhouse in the winter. I think I may give it a haircut, once I figure out the best way to do that.
