I thought of Sedeveria Harry Butterfield? (cross between sedum morganianum and echeveria derenbergii) which I have seen referred to as giant burro's tail- but I don't think it is - the leaves on that one are longer and skinnier.

Rina, that's so interesting, as I have not heard of sedeverias until now. I think you and hablu are right, need to wait for a flower.

new for me too...I found info when looking for ID on this one, bought more than year ago); first I found it named sedum morganianum Giant donkey's tail, also sedum m. Harry Butterfield and then eventually name I posted:

It grows from the leaves as easy as any s. morganianum, it trails but ends seem to turn upwards (I planted few branches in hanging pot); but so far I don't have any branching :

Rina

How cool! Does it flower like sedum or echeverria?

Didn't flower for me yet, suppose to have yellow flowers...
