TREES, SHRUBS AND PLANTS 



Lilacs produce excellent effects when planted in masses on banks 

 with a proper background of trees. 



Mock Orange. The mock orange or syringa bush is another large, 

 high growing shrub that is prized especially for its fragrant white blossoms 

 that are so abundantly produced in June. The old-fashioned variety, 

 Philadelphus coronarius, is the most fragrant but the newer varieties 

 such as Philadelphus coronarius grandiflorus, produce flowers over twice 

 the size and of a purer white. The yellow leaved sorts are not as vigorous 

 or free flowering and should be used very sparingly. The green leaved 

 sorts are very hardy and easily grown on any soil of moderate fertility. 



Snowball. While the old-fashioned Snowball that was formerly 

 planted in every yard is now considered of little value because its foliage 

 is annually ruined by plant lice, its place has been taken by another bush 

 called the ^ Japanese Snowball, Viburnum tomentosum plenum. The 

 flowers of this shrub are quite similar to the common Snowball but appear 

 more attractive and of a purer white against the heavy dark green foliage 

 of the bush. It delights in a rich moist soil and may be planted along 

 the north side of buildings, a northeastern exposure being ideal. Although 

 not entirely hardy in the northern districts, its superiority over the com- 

 mon snowball, both in foliage and flower, makes it a most desirable shrub. 

 There are many other Viburnums also that are used by landscape gar-
