Liquidambar orientalis, commonly known as oriental sweetgum or Turkish sweetgum, is a deciduous tree in the genus Liquidambar, native to the eastern Mediterranean region, that occurs as pure stands mainly in the floodplains of southwestern Turkey and on the Greek island of Rhodes.
Oriental sweet gum is a deciduous tree, 30–35 m (98–115 ft) in height with a trunk of 100 cm (39 in) in diameter. The unisexual flowers bloom from March to April. The fruits ripen in November to December and the seeds are wind dispersed. The tree is very attractive and especially valued for its colourful autumn leaves. Oriental sweet gum trees favour an elevation of between 0–400 m (0–1,312 ft), a mean annual rainfall of 1,000–1,200 mm (39–47 in) and a mean annual temperature of 18 °C (64 °F). The tree's optimal growth is on rich, deep and moist soils such as bogs, river banks and coastal areas but it is also able to grow on slopes and dry soil.
