About Quercus suber – Cork Oak Tree

Quercus suber (Cork Oak) looks excellent as a broad, rounded evergreen tree with year-round grey-green lobed foliage and distinctive corky bark that adds strong textural interest. Its thick, deeply fissured bark not only provides unique visual appeal but also delivers resilience in low-rainfall, poor soil conditions, making it a low-maintenance choice for dryland gardens and Mediterranean-style landscapes.

Reaching 10–15 metres in height with an 8–12 metre spread, Cork Oak offers consistent shade coverage without the seasonal leaf drop typical of deciduous oaks. This makes it well suited for rural properties, estate boundaries, parks, and large garden settings where reliable shade and structure are desired. It also supports local ecology with small catkin flowers and acorn clusters.

For enhanced impact, it looks excellent when underplanted with drought-tolerant groundcovers or native shrubs that complement its Mediterranean character. Its slow growth and sturdy form deliver lasting presence and understated elegance in expansive landscapes.

Preffered Soil

Quercus suber performs best in well-drained sandy or loam soils with an acidic to neutral pH. It will also tolerate poorer, drier soils provided drainage remains reliable. Avoid heavy clay, compacted or waterlogged areas unless significantly improved, as excess moisture can restrict root development and reduce long-term vigour. Keep the soil evenly moist during establishment, then gradually reduce watering as the tree matures and develops its natural drought resilience.
