    Information from Wolfgang:
    turini said:Patty,
    'Murtal' means in English: Valley of the river Mur.

    The river Mur is in Austria, in the province of Styria (Steiermark).

    In that Murtal there grow several Semps in the environment, like S. pittonii and S. montanum ssp. stiriacum.

    And another roller, the Sempervivum globiferum ssp. hirtum (hillebrandtii) from Gulsenberg.
    Gulsenberg means Mount Gulsen (from where we know the S. pittonii as well). This mountain is in the 'Murtal' too.

    This is S. globiferum ssp. hirtum (hillebrandtii) from Gulsenberg, a wild form, only to be found on a small place (like pittonii):
