Northern mountain-ash is a beautiful, cold-hardy ornamental tree prized for its showy white spring flowers and brilliant clusters of orange-red berries that persist well into winter, providing vital food for birds. It performs best in cool climates with moist, well-drained, slightly acidic soils and is an excellent choice for northern or high-elevation landscapes. Once established, it requires very little maintenance beyond occasional watering during prolonged droughts.
