It looks like a cold-hardy and deciduous Sedum.

Yes, hardy sedum, Hylotelephium telephium - 'Autumn Joy'. It grows quite tall and in clumps, eventually needs more space than pot you have now.

....and it will do best outside.

Hey hablu.. Could you post a picture of the whole plant? I think I have something like it in the yard... Never knew!

I have seen a person take cuttings in the early fall and plant them up as house plants and then come spring, plants them out making more plants.

I have them under the old name Sedum telephium spectabile. There are many forms and colors and variation. This is the most common one. Overhere very winterhardy.

They are hardy in Canada z5 too :) Still much smaller than Harry's since we are colder and my plant is in a container.

I'm just keeping in there until it roots. The stem was broken from its roots thanks a lot y'all!

Does it die back in the winter? That is what mine does... Comes up new each spring. Pink flowers. If they are not the same, they look almost identical. They should be hardy here in zone 7.

Edit: By the way, thanks for the pictures, rina and hablu!

It does die back (Jeff mentioned in his post that it is deciduous). And the clump increases slightly every year.

here's a white one: s. spectabile 'Xenos'

Thanks, Missy, for some odd reason I've grown various forms of these for years and never thought to take a cutting, for some reason. I'll put it on the calendar for next year!

Harry,

I think you might mean 'Xenox'? It's a fine one! The one I have in my garden should have a better place to grow.

For anyone interested, these big-leaved Sedums are great signs of spring, if you don't notice the rest of them, that is. From a stump of lone-gone-looking dessicated, blackened stems you get these tiny green bumps that turn into leaves, each day thrilling you a little more. (and new stems - the plants that Rina and Harry have are older, but I don't actually know how large one plant will get. Something else to look into....).
