'''''Sorbus decora''''', commonly known as the '''showy mountain-ash''' or "dogberry" is a [[deciduous]] shrub or very small tree native to northeastern [[North America]].  It occurs throughout the Great Lakes-St. Lawrence Mixedwood forest region, the [[New England-Acadian forest]] region, and the eastern [[Boreal forest of Canada|Canadian boreal forests]].

Showy mountain-ash is very similar to the closely related American mountain-ash.  Like the [[American mountain-ash]] (''Sorbus Americana''), the showy mountain-ash has [[pinnately compound leaves]] and often large clusters of flowers and fruits.  However, a useful distinguishing feature of this species is its shiny, sticky buds <ref>Farrar, J.L. (1995). Trees in Canada. Markham, Ontario: Fitzhenry and Whitside/Canadian Forest Service.</ref>.

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

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

Sorbus decora, Schneid. (S. americana var. decora, Sarg. Pyrus sambucifolia, Gray, not Cham. & Schlecht. Pyrus sitchensis, Rob. & Fern., not Piper. S. scopulina, Brit., not Greene). Small tree or shrub, closely allied to the preceding: lfts. 7-15, oval to ovate-lanceolate, or oblong, obtuse to short-acuminate, serrate, glabrous and dark green above, rather pale and usually pubescent beneath when young, or glabrous. 1 1/2 - 3 in. long: fls. 1/4 – 1/3 in. across, in 2-4-in.-broad and rather loose corymbs, sometimes few-fld.: fr. globose, ovoid when young, red, about 1/3 in. across, with more or less upright calyx-lobes. May. Labrador to Minn., south to N. Y. and Vt. S.S. 4:173, 174.—Often confounded with the preceding species; intermediate forms are not uncommon in regions where the two meet. Both are very handsome in autumn with their large clusters of bright red fr. and particularly S. decora is often planted for its showy fr.
