Mountain ash is a type of tree with distinctive red berries that grows in cold climates. The word is spelled /ˈmaʊntən æʃ/, with the first syllable pronounced like "mountain" and the second syllable pronounced like "ash", but with a short "a" sound. The spelling "ash" is used because the leaves of the mountain ash are similar in shape to those of ash trees. This spelling is important for distinguishing the mountain ash from unrelated trees with similar names, such as the American ash or mountain laurel.
Mountain ash refers to any of several species of small to medium-sized trees or shrubs that are part of the Rosaceae family. These trees are commonly found in the Northern Hemisphere, mainly in the temperate regions of North America, Europe, and Asia. They are deciduous and classified under the genus Sorbus. The term "mountain ash" typically refers to two specific species: Sorbus aucuparia and Sorbus americana.
Mountain ash trees are characterized by their pinnate leaves, which are made up of several small leaflets arranged on each side of a central stem. They produce clusters of small, white flowers during the spring, which are followed by striking clusters of bright red berries in the fall. These berries are an important food source for many birds and wildlife during colder months.
Although commonly known as "mountain ash," these trees are not actually related to the true ash trees (Fraxinus genus) but rather resemble them superficially in their compound leaves. Mountain ash trees are known for their ornamental value, with their attractive foliage, vibrant berries, and occasional brilliant autumn colors. They are frequently planted in gardens and landscapes for their aesthetic appeal.
Additionally, the term "mountain ash" is used informally to refer to certain unrelated species, such as Eucalyptus regnans (also known as Tasmanian oak) in Australia. Despite the different species and variations, mountain ash trees are generally beloved for their beauty, ecological contribution, and ability to thrive in various climatic conditions.

The word "mountain ash" derives from the Old English "æsce" meaning "ash tree". The term "mountain" was later added to distinguish it from other types of ash trees found in lowland areas. The name "mountain ash" is used for several unrelated species of trees belonging to the genus Sorbus. These trees are often found at high altitudes and have similar berry clusters resembling the true ash trees, which led to the use of the term "ash" in their name, even though they are not related to true ashes.
