ORNAMENTAL TREES AND SHRUBS FOR MONTANA 37 



makes a desirable tree. It grows with moderate rapidity to fairly 

 large size, is symmetrical in shape and has a dense foliage of large, 

 nearly round leaves. The flowers, while small and rather incon- 

 spicuous, are delightfully fragrant, and the clusters of berries, with 

 their peculiar wings, add to the interest of this tree. It should be 

 more extensively grown in localities where it will thrive. 



(Tilia ulmifolia) This makes a fairly large tree but is of 

 slow growth. Seeds were planted in the spring of 1907 and since 

 that time the young plants have been entirely hardy. It promises 

 to do well in Montana and will make a desirable ornamental tree.

These form a considerable group of ornamental deciduous trees. 

 Most of the elms, grow into large trees and are very tall and long

 get hardier.

 giving them artificial protection during the winter months. At 

 lower altitudes in the state this tree is hardy and is one of the good 

 trees for street and ornamental planting.

Arrow Wood: (Viburnum dentatum) This is an upright, 

 bushy shrub, growing 12 to 15 feet high. It is a good plant for the 

 shrubbery group and thrives best in moist soil. It is not entirely
