Notes

Western mountain ash (Sorbus sitchensis) is a shrub for native plant gardens, woodland edges, and bird gardens. It is hardy to USDA zone 5, or down to -20°F (-29°C). This plant likes full sun to full shade and moist soil. Small white flowers open in flat-topped clusters in spring and summer. Clusters of reddish-orange berries stay on the plant into winter and feed birds. Fall leaves turn yellow to bronzy-red.

Pairs well with Western hemlock, Duke blueberry, and Aureola Japanese forest grass.
