Our lawn must have marginal tree and shrub beauty, both of leaf and bloom. We want shade, we want shelter, we want imposing effect, we want irregularity of outline: all these things trees and shrubs give us. A few well-placed, naturally grown shade trees are a great embellishment to any place. By making a careful choice of the material which is available we can get beauty nearly all the year. We can have gold, silver, and variegated leafage in both trees and shrubs; we can have ornamental green foliage; we can have evergreens; and we can have floral charm and perfume, as a later chapter will teach us. Here, then, are a few ideas for lawn treatment which will give beautiful and uncommon effects.
