Sempervivums  sp.  ?? 

never seen so many dense white “cobweb”s 

i can see a small insect or two stuck in, …
my first reaction was never seen a insectivorous hens and chicks, that’s what this is : from hens and chicks houseplant group of succulents.
name is Semipervivum arachnoidium.
since the upper lacey thing does look like a spider web.
I have seen it in some european botanical gardens.
you have to scroll down to where they show the cultivars
the extensive white network on the top could qualify.
was this from a show, did you buy it?
if yes could you later share the flower pictures please 

Sempervivum arachnoideum L.
