Flora of Turkey
Turkey has a rich and interesting flora with approximately 9000 vascular plant species (10,765 taxa) from 165 families.
3000 plant species approximately are endemic for Turkey (around 35%). It has a wide diversity of habitats and climatic conditions resulting from geological, topographical and continental characteristics of Anatolia as a meeting place of three phytogeographical regions including Euro-Siberian, Mediterranean, and Irano-Turanian.
*The time I visited this garden, July 2021, the garden was closed because of some constructional or administrative reason, but I was very lucky to find a researcher by coincidence who kindly accepted to guide me discovering the garden and the herbarium.
