324 MANUAL OF GARDENING 



Cherry birch, B. lenta.* 



Well-grown specimens resemble the sweet cherry ; both this and the yellow 

 birch (B. lutea*) make attractive light-leaved trees; they are not appreciated. 



Hornbeam or blue beech, Carpinus Americana.* 

 Chestnut, Casianea sah'vaf and C. Americana.*-f[ 

 Showy catalpa, Catalpa speciosa.'\X 



Very dark, soft-foliaged tree of small to medium size; showy in flower; 

 for northern regions should be raised from northern-grown seed. 



Smaller catalpa, C. bignonioides.\ 



Less showy than the last, blooming a week or two later ; less hardy. 



Japanese catalpa, C. ovata {C. Kcempferi).^ 



In northern sections often remains practically a bush. 



Nettle-tree, Celtis occidentalis* 

 Katsura-tree, Cercidiphyllum Japonicum.X 



A small or medium-sized tree of very attractive foliage and habit. 



Red-bud, or Judas-tree, Cercis Canadensis.* 



Produces a profusion of rose-purple pea-like flowers before the leaves 

 appear; foliage also attractive. 



Yellow-wood, or virgilia, Cladrastis tinctoria.* 

 One of the finest hardy flowering trees. 



Beech, Fagus ferruginea.*'\ 



Specimens which are symmetrically developed are among our best lawn 

 trees; picturesque in winter. 



European beech, F. sylvatica.\ 



Many cultural forms, the purple-leaved being everywhere known. There 

 are excellent tricolored varieties and weeping forms. 



Black ash, Fraxinus nigra (F. sambucifolia).*\ 



One of the best of the light-leaved trees; does well on dry soils, although 

 native to swamps; not appreciated. 



White ash, F. Americdna.*] 

 European ash, F. excelsior.^ 



There is a good weeping form of this. 



Maiden-hair tree. Ginkgo hiloba {Salisburia adiantifolia) .%
