Sorbus scopulina - Ornamental Fruit - Greene's Mountain Ash, Western Mountain Ash Page

Discover the allure of Sorbus scopulina, commonly known as Greene's Mountain Ash or Western Mountain Ash, an enchanting broadleaf shrub native to the picturesque landscapes of the western United States, from southern Alaska to northern California and eastward to the Dakotas and Utah. This unique member of the Rosaceae family flourishes in rocky hillsides, open woods, and alongside streams, often forming dense thickets that contribute to its breathtaking natural habitat.

Reaching heights of 3-15 feet, this deciduous shrub boasts pinnately compound leaves that exude an elegant charm, turning from glossy dark green in spring to vibrant yellow and peach hues in fall, making it a visual spectacle. In bloom from May to July, it unveils clusters of small, fragrant, white flowers, which give way to glossy, orange-red fruit by late summer—an important winter food source for birds like Cedar Waxwings and mammals such as grouse and squirrels.

Hardy to USDA Zone 2, Western Mountain Ash is ideal for gardens that can accommodate its seasonal beauty. While it can struggle with insects and diseases when stressed, its striking fall foliage and decorative berries transform any landscape. With appropriate care and placement in sun or light shade, Sorbus scopulina becomes a cherished part of your outdoor space, honoring the legacy of botanist Edward L. Greene. Whether nestled along hillsides or complemented by streams, this shrub offers both ecological benefits and aesthetic allure, inviting you to embrace its timeless beauty.
