American Mountain Ash (Sorbus americana)

The American Mountain Ash is a native North American tree, valued for its ornamental features and adaptability. It typically grows to a height of 20 to 30 feet with a spread of about 15 to 25 feet, making it a medium-sized tree suitable for various landscape settings. This species is hardy in USDA zones 3 through 6, indicating its suitability for a wide range of climates, including many regions in Canada. The American Mountain Ash thrives in well-drained, acidic soil and prefers full sun to partial shade.

One of the most striking features of the American Mountain Ash is its clusters of bright red berries, which appear in late summer and persist into winter, providing visual interest and a food source for birds and wildlife. In spring, the tree produces white flowers, which are both visually appealing and attractive to pollinators.

The foliage of the American Mountain Ash is also noteworthy, with compound leaves that turn a vibrant red or orange in the fall, adding to the tree's ornamental value. This species is often used in landscaping for its manageable size, striking berries, and fall color.

Native to the cooler climates of North America, particularly the northeastern United States and eastern Canada, the American Mountain Ash has ecological importance in its natural habitat. It is often found in forested areas and along streambanks. In addition to its use in landscaping, the American Mountain Ash holds cultural significance for various Indigenous peoples, who have traditionally used parts of the tree for medicinal purposes.
