About Quercus trojana Webb
Quercus trojana Webb is a small to medium-sized tree that grows 10–20 metres (33–66 feet) tall. It is late deciduous to semi-evergreen, and bears glossy green to grey-green leaves. These leaves measure 3–10 centimetres (1+1⁄4–4 inches) long and 1.5–4 cm broad, with coarsely serrated margins that have sharply pointed teeth. Mature acorns, which develop around 18 months after pollination, are 2–4 cm long and held in a scaly acorn cup. This species ranges from southern Italy east across the southern Balkans (including Croatia, Albania, Serbia, North Macedonia and Greece) to western Turkey. Its distribution is disjunct, with two main population centres in the western Balkans and northwest Anatolia. It grows at low to moderate altitudes, reaching up to 1,550 metres (5,090 feet) in the southern part of its range in southwestern Turkey, and prefers warm, dry growing sites. Quercus trojana is cultivated as an ornamental tree in Britain, Belgium, Spain, and other regions. It has shown very high tolerance to both drought and winter cold. A semi-fastigiate cultivar named 'Iturraran Trinkoa' was selected at the Iturraran Botanical Garden in the Basque region of Spain.
