Fraxinus angustifolia (Narrowleaf Ash) is a deciduous tree species native to southern Europe, including regions such as the Mediterranean and the Balkans. It belongs to the Oleaceae family and is known for its slender leaves and overall graceful appearance.
Size and Appearance: Narrowleaf Ash is a medium-sized tree that typically grows to heights of 15-25 meters (50-80 feet), although it can occasionally reach taller heights. It has a narrow, upright crown with ascending branches. The bark is grayish-brown and develops shallow furrows as the tree ages.
Leaves: As the name suggests, the leaves of Fraxinus angustifolia are narrow and elongated. They are pinnately compound, typically composed of 7-13 leaflets. The leaflets are lanceolate or elliptic in shape, with serrated or slightly toothed edges. The leaves have a dark green color on the upper surface and a paler green color underneath. In autumn, the foliage can turn yellow before falling.
Flowers: Narrowleaf Ash produces small, inconspicuous flowers that are dioecious, meaning individual trees have either male or female flowers. The flowers are typically greenish and appear in clusters or panicles in spring before the leaves emerge. They are wind-pollinated.
Seeds: Female Narrowleaf Ash trees produce winged seeds in the form of samaras. The samaras are flat and elongated, allowing for efficient wind dispersal.
Narrowleaf Ash is adapted to a variety of soil types but generally prefers well-drained soil. It can tolerate both slightly acidic and alkaline soils. It thrives in full sun to partial shade.
