Mountain Ash

Sorbus aucuparia, Sorbus americana

Cultivars: 'Cardinal Royal', 'Autumn Spire', 'Oakleaf'

Mountain ash is a small to medium ornamental tree valued for its feathery compound leaves, spring flowers, and bright clusters of red or orange berries that persist into fall and winter. The airy foliage creates a light, refined canopy that works well in residential landscapes and smaller yards. In spring, flat clusters of white flowers appear, followed by showy berries that attract birds. Fall color ranges from yellow to orange-red, adding additional seasonal interest. Its moderate size and decorative fruit make it a popular accent tree.

Care Instructions

Mountain ash prefers full sun to partial sun and well-drained soils with consistent moisture. It has medium water needs, particularly during establishment and dry periods. Regular watering helps maintain vigor and berry production. Pruning is generally limited to removal of damaged or crossing branches. Winter protection is usually not necessary in cold climates. With proper care, it provides multi-season ornamental value and wildlife interest.
