126 Practical Forestry 



lines of the tree is not good taste, while planting single 

 specimens in open situations should be avoided. 



Of the Poplars there are several upright -growing varieties 

 in addition to the Lombardy, such as the beautiful P. 

 alba Bolleana, a desirable fast-growing tree with a character 

 of its own. 



The Oak, too, has its decidedly upright form in Quercus 

 pedunculata fastigiata, which in old parks is a fairly common 

 tree. A decidedly beautiful small growing tree is the 

 upright form of the dwarf Acacia (Robinia Pseudo-acacia 

 inermis fastigiata) which for confined spaces and wealth of 

 delightful pea-green foliage is a valuable small-growing 

 variety. 



The Elms are not wanting in upright-growing forms, 

 both the English and Scotch being represented, the former 

 in Dampieri aurea, and the latter in Montana fastigiata. 

 A beautiful and distinct tree of upright habit will be found 

 in the fastigiate variety of the Tulip tree (Liriodendron 

 tulipifera fastigiata). 



Cupressus sempervirens, in many parts of England, but 

 particularly by the coast, forms a beautiful tapering ever- 

 green tree with the darkest-green foliage. For clump 

 planting it is particularly desirable, but it is not quite 

 hardy in some parts of the country. Another coniferous 

 tree of naturally erect growth is the red or Virginian Cedar 

 (Juniperus Virginiana), which in sheltered sites is a most 

 desirable member of the family. Two other Junipers are of 

 decidedly strict growth, J. drupacea and J. thurifera. 



The Irish Juniper (Juniperus hibernica) originated in 

 Ireland, most probably as a chance seedling. It is a 

 most desirable shrub, and on account of its singular habit of 

 growing in a compact, slender and graceful column, has 

 proved itself a most valuable evergreen for almost any 

 position, but particularly where geometrical gardening is 

 carried out. The silvery glaucous hue of the thickly 

 produced foliage is extremely beautiful. The nearly allied 

 but much smaller growing J. hibernica compressa forms a 

 compact slender pyramid of bright-tinted foliage and is an 

 excellent plant for rockwork or small gardens.
