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 mountain ash and related
species (most often the European Mountian 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." --
