Sorbus decora, commonly known as the northern mountain ash,[1] showy mountain-ash,[2] Greenland mountain-ash, and dogberry, is a species of deciduous shrub or very small tree native to northeastern North America.

It cannot be found north of 62°15′N, which confines it the southern tip of Greenland, generally deeper up the western fjords, such as the Qinngua Valley.

Showy mountain-ash can be distinguished by its shiny, sticky buds,[6] and its slightly larger flowers and fruit.

[3] It is often cultivated as an ornamental plant for its cold-hardiness, its attractive flowers, and its large clusters of small red berry-like pomes.

The fruits are an important source of food for wildlife, particularly birds in the winter and early spring.
