Sorbus sitchensis

It forms a multi-stemmed plant, either a shrub or small tree, reaching heights of {{Convert|1-4|m|ft|frac=2}}. The winter buds are not sticky, with rusty hairs.

The leaves are alternate, compound, six to ten inches long. There are 7–11 blue-green leaflets, lanceolate or long oval, with a rounded tip and usually toothed from the middle to end. In autumn, they turn yellow, orange and red. The stipules are leaf-like and caducous.

Cymes of 80 or fewer white flowers bloom from June through September (after the leaves are fully grown). The five-petaled flowers are less than a centimetre across. The cymes are flat, compound and three or four inches across.{{cite web | last = Sullivan | first = Steven.

The otherwise similar Sorbus scopulina has yellow-green sharp-pointed leaflets that are sharply serrated over most of their length.

It is endemic to northwestern North America, from the Pacific coast of Alaska, to the mountains of Washington, Oregon and northern California and eastward to parts of Idaho and western Alberta and Montana.
