How to Grow and Care for Aleppo oak

Aleppo oak, also known as Bossier oak

Quercus infectoria is a small tree native of Greece and Asia Minor, with one to two metres (four to six feet) in height. The stems are crooked, shrubby looking with smooth and bright-green leaves borne on short petioles of 3 to 4 cm (1 to 1.5 inches) long. The leaves are bluntly mucronate, rounded, smooth, unequal at the base and shiny on the upper side. The galls arise on young branches of the Quercus infectoria tree when gall wasps sting the oak tree and deposit their larvae the chemical reaction causes an abnormality in the oak tree causing hard balls to be formed. They are corrugated in appearance.
