WHAT SHADE TREES SHALL WE PLANT? 



37 



A variety of trees. The cucumber tree is a large northern 

 representative of the magnolias, a group of trees native to a 

 region farther south. The cucumber is a striking, stately species 

 that ultimately develops into a magnificent specimen for the park 

 or roomy lawn. Its foliage is exceptionally large, clean and pleas- 

 ing. Somewhat similar in size and habit is the tulip tree or white- 

 wood, indispensable where groups and collections of the finer native 

 trees are being assembled. For foliage tropical in its luxuriant 

 richness the great-leaved magnolia (M. macrophylla) , with leaves 

 often 2 feet long, should be selected. This species ought to be given 

 a sheltered corner to protect the heavy foliage from wind injury. 

 The white ash, the American linden or basswood and American 

 beech are trees having a high landscape value and known to succeed 

 over a wide range of country. 



Maples have value. Probably no group of our native trees has 

 been more popular for lawn planting than the maples. The most 

 lasting of our native species is undoubtedly the sugar maple, 

 although the soft or silver maple has been more commonly planted 

 on account of its rapid growth. Sugar maples ought always to be 

 transplanted before they exceed 2 inches in diameter. For securing 

 early results the silver maple 

 has few equals but it can 

 scarcely be considered a sat- 

 isfactory permanent tree. The 

 soft, brittle wood is easily 

 damaged by high winds and 

 most old specimens are very 

 much dilapidated. Wier's cut- 

 leaved silver maple is a won- 

 derfully graceful variety of 

 silver maple with a pendulous, 

 weeping habit. The scarlet or 

 rock maple does best on low, 

 moist lands and colors up in 

 autumn extremely well. 



Gas and smoke resisting 

 trees. A few trees from for- 

 eign countries have high value 

 for street planting through 

 their resistance to dust, gas 

 and smoke. Foremost of these 

 is the Oriental plane or Euro- 



The red oak
