About
The sweet chestnut (Castanea sativa), also known as the Spanish chestnut or European chestnut, is a species of tree in the flowering plant family Fagaceae.
Growing up to 35 m (115 ft) tall and with trunks over 4 m (13 ft) wide, the tree has long toothed leaves. Its long catkins contain both male and female flowers, the latter producing brownish nuts with spiky sheaths in the fall. The tree can live for hundreds of years.
Where it grows
The species is native to Southern Europe and Anatolia. It is found across the Mediterranean region, from the Caspian Sea to the Atlantic Ocean. It is thought to have survived the last ice age in several refuges in Southern Europe, on the southern coast of the Black Sea with a main centre on the southern slope of the Caucasus and in the region of north-western Syria, possibly extending into Lebanon.
