Flora
Vegetation on Hymettus changes from north to south and with altitude. According to the Hellenic Ornithological Society, an Aleppo pine forest grew up in the north after the end of the Second World War, thanks to extensive reforestation around Kaisariani. In the central and southern parts pine gives way to evergreen broadleaf shrubland and phrygana, and at 800 to 1,000 metres shrubland dominates.
On the same source’s habitat map, shrubland covers 62.8% of the area, artificial landscapes 15.2%, forest 14.4%, grassland and pasture 5.1% and rocky areas 2.6%. The forest share is small compared with the "green mountain" picture one has from afar.
Aromatic plants gave the mountain its fame. Kathimerini reports that the slopes are largely covered by herbs, above all thyme, which made the honey of ancient Attica famous. Pliny the Elder, and Virgil before him, praise thyme honey.
