Sideritis, the tea of our mountains, is found throughout the Mediterranean basin to 100 different species.

In Greece there have been identified 11 of them. Each region, due to the many different microclimates, hosts different kind.

So in Crete we find the kind Sideritis syriaca, in Peloponnese in Sideritis clandestine, in Central Greece the Sideritis raeseri, in Euboea Sideritis Eyboea, at Mount Olympus area and in Macedonia Sideritis Eyboea while the peninsula of Athos in Sideritis Athoa etc. Many of these species have many subspecies because the plant has a high tendency to hybridize to adapt to the conditions, which is why their recognition by scientists is a difficult and painful process.
