Sorbus alnifolia (Korean Mountain Ash)

Korean Mountain Ash


An ideal specimen tree for small gardens, Sorbus alnifolia (Korean Mountain Ash) is a small, densely-branched, deciduous tree with a long season of interest. It grows quickly and its upright branches form a dense, rounded canopy, which casts dense shade below. The elegant foliage of glossy, ovate, dark green leaves, 2-4 in. long (5-10 cm), warms up to gold and orange in the fall, before falling to the ground, revealing the dark or pale gray, finely-striped bark. In late spring, a profusion of tiny white flowers held in flat-topped clusters are produced. They are quickly followed by abundant clusters of showy, orange to red fruits in fall. The berries persist well after the leaves are gone, providing a welcomed feast for various types of weary, migrating birds. Attractive in form, elegant in flower, colorful in fruit and foliage, Sorbus alnifolia stars in almost every season of the year.

  • Grows with a pyramidal shape when young that rounds with age. Can reach 40-50 ft. in height (12-15 m) and 20-25 ft. in spread (6-8 m).
  • A full sun or light shade lover, this tree is easily grown in acidic, moderately fertile, humus-rich , well-drained soils. Some drought tolerance.
  • Perfect specimen tree for city gardens or woodland gardens. Perfect for small gardens!
  • No routine pruning necessary. Remove diseased, damaged, congested or crossing shoots.
