Thank you for respond! I thought the same, but we'll see...

Looks a lot like Sedum to me as well, kind of reminds me of Sedum versadense, but I can't tell from the picture if it has little hairs on it or not. So possibly Sedum stahli I think is how you spell the name.

Does it grow outside year round? How low are the winter temperatures?

Thank you, Nicholas!

It doesn't have hairs. I googled both Versadense and Stahlii and it looks more to Sedum Stahli, but it appears to be native to Mexico?

I found something similar online:

Sedum atratum L. subsp. atratum

And this one of the photos that I captured:

rina_Ontario,Canada(5a)

Temperatures are very low, sometimes even -30 degrees Celsius and it is always covered by snow during winter. It grows every year - I find many of these every spring all over the mountain.

Flowers are often best to ID the plant; flowers of S. atratum look much more similar to your plant. It is listed as hardy to z3 (more what yours temps are), where the other 2 sedums mentioned are listed as hardy to about -12*C at most. S. atratum is native to Alps, Pyrenees and Carpathians Mountains.

Nice plant. I would like to find one around here...

It Proba ly isn't a species common in cultivation. I'd Google some university botany departments in the country where you found it, or somewhere nearby. You can also try horticultural societies in the area. You photo is especially good for ID since you've included the spent seed capsule in it.

Thank you everyone!
