Common or cobweb houseleek(?)

At the south side of the Texel Group, near the Dicker Alm. The climate in this part of the group is relatively dry, which is why these succulents feel right at home. It's a houseleek, and my guess it that it's a common houseleek (Sempervivum tectorum), but it could also be a cobweb houseleek (S arachnoideum) or a cross between several species. 16 July 2013.
