It is an endemic of Cyprus of limited distribution. As far as I can tell, it is related to S. fruticosa. It may be listed as restricted on the CITES list. Robin or Christian may be able to tell you if it is available in Europe. It and S. desoleana were discovered relatively recently, and desoleana is an endemic from either Corsica or Sardinia. This one is related to clarey sage and is available as seed.

Take a look at Mountain Valley Growers they have
S.fruticosa (Greek Sage)with some good pictures too.
