Sorbus koehneana, commonly known as Koehne Mountain Ash, is a deciduous small tree or large shrub native to the mountainous regions of Western China. It typically grows to a height and width of 10-15 feet (3-4.6 meters), with a rounded habit and a moderate growth rate. The leaves are pinnate with several pairs of leaflets, turning a brilliant red in the fall, which is one of its most notable ornamental features.

Koehne Mountain Ash is valued for its clusters of white flowers that bloom in late spring to early summer, followed by showy white berries that persist into winter, providing food for birds. It is often used in residential landscapes for its attractive foliage, flowers, and fruit, and can be planted as a specimen or in small groups. This species prefers well-drained, loamy soils and can tolerate part shade, though it flowers best in full sun. It requires medium amounts of water and benefits from mulching to maintain soil moisture. While generally low-maintenance, it can be susceptible to fireblight and other diseases common to the Rosaceae family. It is not known to be invasive and does not have aggressive roots, making it a suitable choice for gardeners looking for a small, non-problematic tree.CC BY-SA 4.0
