Sorbus aucuparia, more commonly called
rowan and
mountain-ash (although the latter name may be used for several
other unrelated trees), is a species of deciduous tree or shrub in the
rose family. It is a highly variable species, and
botanists have used different
definitions of the species to include or exclude trees native to certain areas; a recent definition includes trees native to most of Europe and parts of Asia, as well as northern Africa. The range extends from
Madeira and
Iceland to
Russia and northern
China. Unlike many plants with similar distributions, it is not native to Japan.
