The pink flowers of the cyclamen like the shadow of the Mount Athos forests. The image above is from the book early 19th century botanical book Flora Graeca.
The oleander is often to be found in or around the monasteries.
The monastery of Konstamonitou and the harbour of Dafni.
The Ferula Nodiflora I saw uphill near Lavra.
The Ferula Nodiflora with green beetles above Lavra.
The Euphorbia Dendroites likes the rocky ground.
In Thebais the plant even grows on the stone wall
But Euphorbia will not only grow on rocky soil even on the Dutch clay it is doing well. This is the small front yard of my home in Haarlem, The Netherlands. So when I look out my window something reminds me of Athos.
