Sorbus americana – American Mountain-Ash

American Mountain-Ash

The mountain ash and related species (most often the European Mountain ash, Sorbus aucuparia) are sometimes referred to in folklore as “Rowan” trees, but this use has almost disappeared from the modern lexicon. The rowans were thought by the Celts and other primitive peoples of The British Isles to have magical properties.

“Mountain ash, 1804, from rowan-tree, rountree (1548), northern English and Scottish, from a Scandinavian source (cf. O.N. reynir, Swed. Ronn “the rowan”), ultimately from the root of red, in reference to the berries. The rowan “was the tree most often credited with protective magical powers against all effects of witchcraft, not merely in Celtic areas but throughout Britain.” — Oxford Dictionary of English Folklore

The bright orange berries persist through winter, making this tree and outstanding ornamental for specimen plantings. Native populations are listed as endangered by the State of Illinois.

American Mountain-ash is relatively small (maximum height 40 feet) deciduous perennial tree, native to northern North America. Its conspicuous white spring flowers and outstanding, persistent orange fruit make it one of our most recognizable trees. It is well adapted to both coarse and fine soil textures, but has a low tolerance for drought or fire, and virtually no tolerance for salt aerosols. It grows best in full sun but can tolerate some shade.
