Narrow-leafed Ash is a species of Fraxinus native to central and southern Europe, northwest Africa, and southwest Asia.
The Narrow-leafed Ash has an average life between 120 and 200 years. Over its life reaches up to 25 metres height and can offset 780 Kg of Co2. The trunk reaches up to 1.5 m diameter..
The bark is smooth and pale grey on young trees, becoming square-cracked and knobbly on old trees. The buds are pale brown, which readily distinguishes it from the related Fraxinus excelsior (black buds) even in winter. The leaves are in opposite pairs or whorls of three, pinnate, 15–25 cm long, with 3–13 leaflets; the leaflets being distinctively slender, 3–8 cm long and 1–1.5 cm broad. The flowers are produced in inflorescences which can be male, hermaphrodite or mixed male and hermaphrodite. The male and hermaphrodite flowers occur on all individuals, i.e. all trees are functionally hermaphrodite. Flowering occurs in early spring. The fruit when fully formed is a samara 3–4 cm long, the seed 1.5–2 cm long with a pale brown wing 1.5–2 cm long. This tree grows very rapidly. In Mediterranean regions it tends to grow in cooler areas at higher elevations or along rivers and wetlands. It can be found as dominant or secondary species in mixed broadleaved forests.
