Mountain ash, also known as Sorbus aucuparia, is a deciduous tree native to Europe and parts of Asia. It typically grows between 15 to 25 meters tall and is recognized for its striking clusters of white flowers in spring and bright orange-red berries in autumn. The tree thrives in well-drained soils and is often found in mountainous regions. The wood of the mountain ash is strong and flexible, making it useful for various applications, including furniture and tool handles. Additionally, the berries are rich in vitamin C and can be used to make jams and jellies, although they are often too bitter to eat raw.
