Quercus suber

Common Name:
Cork Oak

Description:
Quercus suber, commonly known as the Cork Oak, is a long-lived evergreen oak tree native to the Mediterranean region. It is best known for its thick, deeply furrowed bark, which is harvested sustainably to produce cork. The rugged, gnarled trunk and wide-spreading canopy give this tree a distinctive and picturesque appearance, making it an excellent feature tree for large gardens and landscapes.

The Cork Oak has dark green, leathery leaves with a silvery underside, providing year-round interest. It is highly drought-tolerant once established and thrives in well-drained soils, including sandy and rocky conditions. This species prefers full sun and is resistant to coastal conditions, strong winds, and light frost. Its small acorns serve as a valuable food source for wildlife, including birds and mammals.

With its unique bark, resilience, and historical significance, Quercus suber is an excellent choice for Mediterranean-style gardens, avenue plantings, and ecological restoration projects.
