The showy white flowers appear in early summer, and the abundant orange fruit appear in summer, persisting through winter. Fruit provides palatable browse for many animals and birds, but is not suitable for human consumption, except, perhaps for various folk remedies; the plant is not toxic.

The Sorbus genus covers about 190 different species of deciduous trees and shrubs, found mainly in northern temperate regions, in woodland, on hills, mountains and on scree. Sorbus species and cultivars are prized for their ornamental qualities. Their leaves are decorative, and may be either simple or pinnate, and often color well in autumn. Their flowers are a second plus point. They grow as terminal corymbs of small, white or rarely pink flowers in spring and early summer. These are followed by round or oval berries that may be white, yellow, orange, red or brown.

The mountain ash and related species 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
