Quercus suber
Cork Oak
Description
Cork Oak (Quercus suber) is native to the Mediterranean and is known for the useful bark that is used for wine bottle stoppers and flooring. This beautiful tree can reach 70’ tall and wide with an irregular, free-form canopy. When it is young, it works well planted with other California natives, but as it matures, it will take up the space around it, and most of the companion plants will become enveloped in the canopy if they are not moved. This is not a very desirable choice for a small garden, but if the property has large open spaces, this can be a great addition if it is left alone to grow naturally. This tree should be planted at least 10 feet away from any hardscape areas, 20 feet from structures such as houses and buildings, and not near any powerlines. Shrubs and perennials should be planted about six feet away from this tree. It should be irrigated for about 45 minutes once a week when using most in-line drip irrigation systems.
