Its deciduous leaves measure from 7 to 14 cm long and 3 to 5 cm wide, with 6 to 12 triangular lobes on each side. This is a monoecious tree, with male flowers in the form of hanging catkins and discrete female flowers often grouped together near the axils of the leaves.

This tree comes from Southeast Europe (Italy, the Balkans, etc.). In France, it is mainly found planted, especially in the Centre-West, and rarely grows spontaneously.
The turkey oak grows well in clay soil, but also tolerates calcareous land.
The pink coloured wood of this species is heavy, hard, sinewy and not very durable. It is mainly used for railway ties and roof frameworks.
