Quercus suber (cork oak)
Quercus suber originates primarily from the western Mediterranean region. It is particularly widespread in Portugal, but can also be found in Algeria and Morocco. It is very drought-resistant, but not hardy in Central Europe.
A single tree can produce up to 200 kg of cork in its lifetime.
The cork oak is evergreen and grows up to 20 meters high. The leaves are leathery and have serrated edges.
