  • Arboretum Treasure: Sorbus caloneura

Blooming beautifully right now on the south end of the Arboretum’s prized mountain ash collection is Sorbus caloneura, an unusual small tree native to the forested mountains of western, central, and southern China.

In the latest issue of the Arboretum Bulletin, professor emeritus of horticulture at Edmonds Community College Walt Bubelis profiles the tree and discusses the history of the Arboretum’s two specimens.

“All in all, it’s an easy and reliable plant to grow and is worth seeking out,” writes Walt. “It’s small enough for most gardens and can be grown as either a shrub or tree, adding variety of form to its variety of seasonal colors.”
