Quercus suber, commonly called the cork oak, is a medium-sized, evergreen oak tree in the section Quercus. It is the primary source of cork for wine bottle stoppers and other uses, such as cork flooring. It is native to southwest Europe and northwest Africa.
It grows to up to 20 m (66 ft), although it is typically more stunted
in its native environment. The leaves are 4 to 7 cm (1.6 to 2.8 in)
long, weakly lobed or coarsely toothed, dark green above, paler beneath,
with the leaf margins often downcurved. The acorns are 2 to 3 cm (0.79 to 1.2 in) long, in a deep cup fringed with elongated scales.
Cork oaks can live 200 to 250 years, and are considered to be soil builders and their fruits have been shown to have useful insecticidal properties.
