Crete has a rich biodiversity and the best moment to witness this is in the spring when the flora is at its best. Over 1.700 species have been recorded up to date in Crete, many of which are endemic. Some remote areas of the island, especially the White Mountains and the surrounding islets are home to many stenoendemic species and subspecies, i.e. plants that are only distributed in this limited area.
Every year these rare species attract botanists from all over the world. They come to study wild flowers, including impressive native Cretan orchids. Moreover, endemic tulips grow on the White Mountains, on the Dikti range, on the Gramvousa peninsula and in the small botanical paradise of Gious Kampos in Rethymnon.
Crete is also famous for its aromatic plants and herbs that grow everywhere on the island. Many of them have been used since ancient times for their therapeutic properties and they are currently cultivated in many places of the island.
Great Britain, whose area is 40 times larger than the island of Crete, encompasses almost the same number of species of plants. This is indicative for the variety of species available on the island.
Dittany (Origanum dictamnus) (Greek: diktamos) is an endemic herb of Crete, the most famous of all, which is mainly used as a tea and as a therapeutic sip. Its name is taken after the Dikti Range (Lassithi Mountains), though it is also met in all ranges of Crete.
Cretan zelkova (Greek: Anegnoro or Ampelitsa) (scient. Zelkova abelicea) is an endemic bush or small tree of Crete as high as 3-5 meters. It constitutes a unique species of the genre Zelkova, of the family Ulmaceae and is characterized as a living fossil. It took the name "Anegnoro" (i.e. unknown) because when it was discovered, nobody knew its species.
The holly or Kermes oak is a species that resembles common oak. In Crete it is met in all mountainous regions and is one of the most common trees. The oaks are met in ranges of Crete, as they can grow in rocky and dry soils and withstand the extreme weather conditions there. Indeed, the beautiful oak forest of Rouvas is the largest grove of oaks in Europe.
The plane tree can be met in every place of Greece (valleys, ravines, lakes, river banks and village squares). It also found almost everywhere in Crete and is one of the most typical plants of the Cretan flora. Perhaps no other tree, except the olive tree, is so closely associated with the daily life of the Cretans, as the plane tree because has been the spectator of all historical local events.
The carob tree can be met everywhere, even on the sidewalks, because of the dense shade and the zero care it needs. Its name (ceratonia) means horn in Greek and is taken after the shape of its edible seed pods. Carob tree can reach a height of 18m and the age of 100 years, while its leaves are round, hard, dense and frost- tolerant. It grows in the arid and rocky coastal areas of the island at an average distance from each other.
The cedars of Crete (Juniperus macrocarpa and Juniperus phoenicea) form some of the most important ecosystems in Greece, the cedar groves on the dunes of southern Crete. The ecological importance of the dunes is enormous for the biodiversity and the existence of rare animals and plants.
The palm of Theophrastus (Phoenix theophrasti), also known as Cretan Date Palm is a rare endemic species of the Aegean Sea, which is met all over Crete, in several Aegean islands and in Antalya (southwestern Turkey).
The Cretan cephalanthrera (Cephalanthera cucullata) is an endemic species of orchid that grows exclusively in the mountain forests of Crete, at an altitude of 700-1500m. It is a perennial herbaceous plant with short, creeping rhizomes. Its height reaches up to 20cm and it develops up to 24 whitepinkish flowers from May to June, but it does not bloom every year. In late June the seeds ripen and the aboveground plant parts dry.
