Discover the captivating beauty of Sorbus alnifolia, commonly known as Korean Mountain Ash and Alder Mountain Ash, an exceptional deciduous ornamental tree that will transform your landscape. Perfect for cool northern climates, this Asian native thrives in USDA Zones 3 to 7, offering a moderate to fast growth rate, ultimately reaching heights of 40-50 feet and spreading 20-25 feet. Admire its pyramidal youth, maturing into a majestic rounded form that graces any garden setting.

In May, watch as dense corymbs of creamy white flowers emerge, creating a stunning display that precedes the development of pink to scarlet berry-like pomes, which persist through fall into the winter months, attracting birds and adding an appealing contrast against the smooth, gray, beech-like bark. The tree’s simple, dark green, glossy leaves transform into a spectacular golden-orange showpiece come autumn.

Korean Mountain Ash's robust nature includes noteworthy pest resistance, making it a preferred choice over other Sorbus species. Despite some susceptibility to diseases like bacterial fireblight and scab, its overall hardiness and low maintenance needs make it an ideal specimen for lawns and shaded areas. However, be cautious of its intolerance to urban pollution. Enjoy this tree's visual and ecological benefits in your landscape today, or wherever a sophisticated, non-intrusive shade tree is desired.
