American Mountain Ash

Scientific name

Sorbus americana

Description

American Mountain Ash is a medium-sized tree that typically grows up to 10 m tall. The leaves of American Mountain Ash are compound, with 13-17 leaflets that have toothed margins and are 5-10 cm long. This species produces a full, symmetrical crown which grows clusters of small white flowers during the spring. The flowers develop into bunches of berries that turn a vibrant red-orange colour in the fall. Several bird species are drawn to the berries, making it a favourite tree to plant among bird watchers.

Planting conditions

American Mountain Ash grows best in moist, well-drained soils that have an acidic pH. It will also grow well in dry or rocky habitats, but will be shrubbier in appearance. It thrives in full sun, but will also tolerate part shade conditions. American Mountain Ash can naturally be found growing in woodlands, edges of swamps, rocky hillsides, and roadsides.
