Julia, it's no tectorum if it has those tufts of hair. It looks like an F1 arachnoideum X tectorum or marmoreum hybrid from your picture I would think more likely the latterbased upon shape and color but it's only a guess..
I don't grow or never have seen the plant but you can tell by the growth habit that is not only tectorum and maybe not tectorum at all IF you have the real McCoy!
