Fraxinus is a noun that refers to a genus of deciduous trees belonging to the Oleaceae family. Commonly known as ash trees, the Fraxinus genus comprises around 45 different species, mainly found in temperate regions of the northern hemisphere. These trees are known for their tall stature, with some species growing up to 100 feet (30 meters) in height.
Fraxinus trees are characterized by their compound leaves, pinnately arranged in rows opposite to each other along the branches. The lanceolate leaflets are typically serrated along the margins and often possess a glossy, dark green color. In autumn, these leaves turn vibrant shades of yellow, orange, or purple before dropping off in winter.
The Fraxinus genus produces small flowers, either in clusters or individually, which typically do not have any petals but are instead composed of inconspicuous sepals. These flowers are usually wind-pollinated, as they lack showy petals or fragrances to attract insects for pollination.
Ash trees are valued for their wood, which is renowned for its strength, elasticity, and resistance to splitting. The timber is often used in furniture making, flooring, and tool handles. Additionally, ash trees have ecological importance as they provide habitats for numerous bird species and support a variety of insects.
Despite their many benefits, ash trees are susceptible to diseases such as ash dieback, caused by the fungus Hymenoscyphus fraxineus. This disease has had a significant impact on ash tree populations across Europe.
