...perhaps a Jovibarba? (related to Sempervivum).

Maybe Sempervivum Koko Flannel...there are many named and unamed varieties of semps, as they cross super easy. I have bought here many times and find thier plants are great and the site can be a goo reference to figure out ID too@

'Koko Flannel' seems to have red tipped and 'tufted' leaves - just looking at their photo.

Just in case it blooms, pls. post a photo of blooms. They may help to ID - at least the genus.

Similar to Sempervivum 'Forest Frost' , but not quite.

Yes Rina, I noticed that too. Maybe you know this but some may not... many/most semps have seasonal color, including tips or edges that are only revealed in spring, or summer, or winter...not like most succulents that color with heat and cold, semps are just all very individual in terms of when they color or go all green. Yet another reason they are so hard to ID, but so fun to grow!

Yes Lisa, I am aware of the color change of succulents according to seasons, and also growing conditions. I have seen very similar plants as OP's plant, in many photos from different sources, and they do not look like they get such red tips, and also 'tufts' at the tips. Of course, I could be wrong....I am sure there are lots I didn't see :)

I have many semps, in ground and in containers. I do not have one looking same (or very similar) to either OP's plant or 'Koko Flannel', so maybe I shouldn't comment. Semps I have grow outdoors year-round and experience quite a temps change in my zone - having real winter season.

There are so many hybrids out there and many are so similar looking, they are very difficult to ID. Species perhaps little easier - I am not sure...They grow in 'wild' in mountains of Europe, and we called them all just hens & chicks...
