A very familiar evergreen oak from the western Mediterranean. Cultivated from antiquity for its cork, the cork being harvested once every seven years. The irregular crown starts off oval but later becomes broader, more or less rounded. The soft bark is greyish-brown and only develops deep grooves after the fourth year. Once the bark has been harvested, the trunk is a fiery red colour. The evergreen serrated leaves are oval to ovoid and glossy dark green. On the underside they are felt-like and greyish-white. The elongated ovoid acorns grow singly or in pairs and are 1.5 - 3 cm in size. They are one-third or half enclosed by the cupule. Q. suber can flower practically the entire year, which means that the acorns are visible most of the year. Quercus suber is an evergreen oak that has been cultivated from antiquity as a supplier of cork. The corky bark may be harvested only when the trunk has a diameter of approx. 60 cm.

Quercus suber is среднерастущий and can eventually reach a height of 6 - 15 (20) m, depending on the site and climate conditions.
The right time to plant Quercus suber is during the dormancy period. In Western Europe, Quercus suber with root balls can generally be planted from mid-November to late April, although this depends strongly on the climatic conditions and the species of tree.
