Description of Trees 173 



more permanent trees have reached a good growth, when 

 they can be removed. 



Redbud or Judas-tree {Cercis canadensis). — This is 

 a very beautiful small tree, often taking the shrub form, 

 producing an abundance of bright pink flowers before the 

 leaves appear. The latter are of a very dark rich green 

 color that is ornamental all summer. If gro^^Ti too rapidly 

 while young, it often winter- kills, hke many of the trees 

 coming from the middle and Southern States, and succeeds 

 better in the lawn than if planted in a rich border; enough 

 plant-food, however, must be used to produce a fairly 

 vigorous growth. 



Flowering Dogwood {Cornus florida), Fig. 95.— This 

 small tree requires some protection from the hot sun and 

 drying winds of winter to reach its greatest perfection. In 

 full exposure the large white bracts about the flowers — the 

 ornamental part of the blossoms — are often injured, but 

 under the shade of larger trees, on the north slope of a hill 

 or in the shade of buildings and in rather moist soil, it 

 becomes one of the most beautiful of our native small trees. 

 The pink or red form of this species is also very beautiful 

 and valuable. 



English Hawthorn {Cratoegus Oxycantha), Fig. 96. — 

 The double-flowering hawthorns are among the most beau- 

 tiful of the small trees. The flowers are very brilliant 

 and abundant and the foliage is of a beautiful dark-green 

 color, but, like all the rosaceous plants, the flowers are of 

 short duration. The tree is subject to the attack of both 

 •the flat- and round-headed apple-borers and San Jose scale, 

 and the leaves to several species of fungi, for treatment of 

 which see chapter on Insects and Fungi. The varieties known 

 as Paul's new double white and red are among the best. 



Golden-chain or Laburnum {Laburnum anagyroides) . — 

 Where this half-hardy shrub or small tree succeeds, it is one of
