Unknown Sedum

I grew this plant as Rhodiola kirilowii but it is certainly a sedum (or hylotelephium) akin to kamstchaticum. The plamnt is about 10-12" tall so much taller than the two cultivars of kamtschaticum I currently have. Anyone recognize it?

Todd, I have the same plant, but grown as Sedum kirilowii.  I have always suspected it is wrong but never bothered to check out what it might actually be.  It seeds around too much and I pull most of the seedlings out.  Possibly it is S. aizoon as Lori suggests.  Maybe in 2011 I'll give it a harder look to apply a proper name, or I might pull it out altogether.

It's not  Rhodiola kirilowii but almost definitely Sedum aizoon. R. kirilowii has yellow/red flowers and is not as bushy. See http://www.efloras.org/florataxon.aspx?flora_id=2&taxon_id=200009841 for the Rhodiola. Lori's pics of S. aizoon are quite compelling as well.

What about this one:Sedum hyperaizoon (syn. Aizopsis hypera)

Here's some info on "Sedum hyperaizoon":http://books.google.ca/books?id=Jo9VgQAsMtkC&pg=PA153&lpg=PA153&dq=sedum...

(Same book as I linked to above; looks like a good reference - I'd like to get it!)

Thanks guys...I always thought aizoon and kamtschaticum were synonyms, but i guess not!  My mystery is certainly of the aizoon group and does look much like the hyperaizoon or maximowiczii.  Mine has never self-seeded.  I like it well enough.
