34 MONTANA EXPERIMENT STATION 



THE MOUNTAIN ASHES. 



These are among the very best ornamental trees and shrubs 

 which are adapted to growth in Montana. They have a beautiful 

 foliage and the fruits, which are very conspicuous, often remain on 

 the trees until late in the winter. 



European Mountain Ash : (Sorlni-s Aucuparia) This plant 

 is a native of Europe, western Asia and Siberia. It grows into a 

 round headed tree from 20 to 40 feet high. It is hardy at this station 

 and is one of the very good trees for lawn planting. It is not, how- 

 ever, large enough for street or park planting. When placed on 

 the lawn it produces very beautiful effects. The trunk of the tree 

 is more or less subject to sun scald on the south side during the 

 winter months, and until the trees are four or five years old some 

 shade should be provided for the trunks at that season. 



American Mountain Ash: (Sorbus Americana) This plant 

 grows into a small tree or large shrub and is desirable for orna- 

 mental purposes. It is hardy at this station. 



Western Mountain Ash : (Sorbus sairibuci folia) This grows 

 into a small tree or shrub and is a desirable plant for ornamental 

 purposes. It is native to Montana. 



Red Choke Berry: (Sorbus arbutifolia) This is a shrub 

 which grows to a height of from 6 to 12 feet. It is hardy at this 

 station and deserves a place in the shrubbery. 



Oak - Leaved Mountain Ash : (Sorbus querci folia) This 

 plant grows into a small tree, pyramidal in form. The leaves have 

 much the same shape as those of the white oak. At this station it 

 is a slow growing tree, but quite hardy and is desirable for orna- 

 mental purposes. 



THE SPIRAEAS. 



These form a large group of ornamental deciduous shrubs, with 

 alternate leaves. The flowers are usually small, white, pink, or 

 crimson in color and borne in umbels, corymbs, or panicles. They 

 c.re mostly low growing shrubs and are well adapted to the borders 

 of roads, walks or shrubberies, or as single specimens on the lawn. 

 They are propagated from seeds, and from hard wood cuttings. 



Douglas Meadow Sweet: (Spiraea Douglasii) This shrub 

 orows to a height of about 8 feet. The branches are brown; leaves
