    This wonderful tree from North Africa and Southern Europe is best known for its thick furrowed bark which provides the cork of commerce. Cork is not harvested from the trees until they are 30-40 years old, and then it is harvested every 10 years or so. A lovely wide-spreading tree to 40-70', the cork oak has small, leathery leaves and makes a wonderful attractive specimen. In Portugal there is a delightful tree called the 'Monumental Cork Oak' which is 250 years old, 16 meters tall and requires at least 5 people to encircle it! S/M-D

    zz This 65 x 40 ft. evergreen oak produces the cork that we know. The native range is Southwest Europe and northwest Africa. If the corky bark is harvested sustainably every 10 years or so, this can actually accelerate carbon sequestration. The tree is frost sensitive but can be grown most successfully in places without significant freezing.

    You probably know the outer bark of this tree very well, having pulled chunks of it out bottles of wine. This is the cork oak, with the very distinctive and useful thick, spongy layer of bark called cork.Strangely, the cork can be stripped off living trees without harming them, allowing them to regrow a new layer which is then harvested again and again after it regrows. If you've decided to get into wine making, you really need one of these on your property as well. Quite tender, zone 8.

    This is the tree from whence most commercial cork is derived; the strange twisted trunk develops a thick, deeply furrowed corky bark that is harvested in Spain, Portugal and in other parts of the Mediterranean region. Mature trees can reach 60' tall and form a broad canopy of toothed, shiny dark green leaves that are silver-gray beneath. Chocolate brown acorns are held loosely in caps and provide food for bird and beast. Plant in deep, well-drained soil in full sun and provide moderate water. Hardy to 10F. Southern Europe, Northern Africa.

    This is THE source of those real corks that we pop out of wine bottles! Beautiful round headed trees, usually 40’ in a landscape with dramatic fissured thick corky bark. Elegant evergreen specimen tree with nice semi open branching habit as it matures.

    The famed cork oak from the savannas of southwestern Europe, indeed used for repeated harvest of the real thing! Coming from our mirror climate, this makes a most beautiful and useful street or garden tree, reaching an eventual 50', with thickened, orangey bark and rounded, evergreen leaves, somewhat shedding briefly in early spring as the new leaves emerge. (By the way, pigs love the acorns ... just saying.) Accepts a fair amount of garden water but most at home with long summer drought. Frost hardy in USDA zone 7.
