Quercus suber plant

The cork oak, scientifically named Quercus suber, is an evergreen oak that comes from the central and western regions of the Mediterranean. It is a medium-sized oak tree that typically grows to heights of 40-70 feet and holds both commercial and aesthetic value. 

The leaves are simple, arranged alternately, and have an ovate to oval-oblong shape, measuring 3-7 cm in length. They have an acute tip, a somewhat rounded to cordate base, and 4-5 small teeth on each side of the margin. The upper surface of the leaves is glossy green, while the lower surface is covered in a white-gray tomentose layer. The leaf stalk, or petiole, is 8 to 15 mm long. The cork oak produces acorns, which are ovoid-oblong in shape and measure 1.5-3 cm in length. The acorns have a cup-shaped cap and a short stalk connecting them to the tree.

The cork oak has a distinctive appearance with its short trunk, thick branches, and rounded crown. Its trunk and major branches are covered in corky bark, which can be harvested from mature trees and used to make various products, including corks for wine bottles.

To thrive, the cork oak requires acidic, well-drained soils that range from moist to dry. It can tolerate full sun exposure or partial shade. This oak species is low-maintenance, resistant to deer, and can withstand drought conditions. It's important to be aware that oaks, including the cork oak, contain high levels of tannins in their leaves, bark, and acorns, which are toxic to horses.

The cork oak is tolerant of hot summers with prolonged droughts and mild, wet winters. While it is native to the Mediterranean basin, it can be grown in regions that have a Mediterranean climate.
