The mountain ash grows in western and central Europe from lowland to high mountain elevations up to the tree line, and, in northern Europe, even beyond the Arctic Circle. It is resistant to frost, thrives on poorer soils and is important as a pioneer tree which, because it is distributed by birds, quickly covers burned and logged areas. It reaches a height of only 15 to 20 metres. The bark is smooth and grey-brown, the buds are elongate, dark brown with greyish hairs.
A comparatively small tree, it grows to a height of 10 to 20 metres, and develops a dome-like crown with erect branches and thorny twigs. The bark is furrowed in squares. The alternate leaves have a stalk almost as long as the blade. The abundantly borne white flowers appear in April and early May. The rounded fruit is borne on long stalks, and is yellow-green when ripe. The wild pear has deep roots and favours light, deep soils.
The mountain ash, and its several cultivated varieties, is also popular for planting alongside roads as an ornamental for its spring flowers and bright autumn coloration. The wood has little durability.
The service tree grows in North Africa, Asia Minor and southern Europe, as far north as central Germany. It is sensitive to frost, and requires a mild climate and a fertile, mineral-rich soil to grow well. A slow-growing tree, it reaches a height of 10 to 15 metres, but because it may attain an age of 500 to 600 years one occasionally sees a tree that is 20 metres high.
Unlike the mountain ash, the reddish brown bark is longitudinally fissured, even in the young tree. The leaves, odd-pinnate, and grey-downy beneath until midsummer, appear about 14 clays later than in the mountain ash. The service tree begins to bear flowers and fruit at the age of 25 to 35 years, sometimes sooner.
The berry-like fruit is broadly ovoid and scarlet. The stalk and remainder of the calyx are covered with whitish down. It is an important tree in the afforestation of karst areas and is a popular ornamental in city parks and gardens. Growing in the high mountain alpine zone is the shrub form Sorbus chamaemespilus Grantz., with leaves that are hairless below.

In garden planning, a visual barrier is often desirable for shelter and privacy. Plants themselves from a temporary screen, serving to separate two areas of the garden.
