ADAPTATION OF CONIFERS 47 



pine is a beautiful object standing alone on the edge of a lawn. 

 It is highly ornamental under varying conditions and with its 

 horizontal branches, slightly curving upwards, succeeds well 

 in light sandy soils. 



The pyramidal white pine, Pinus Strobus var. fastigiata, is 

 a noble plant in formal gardening. It does not appear to have 

 been in cultivation many years and specimens are not known 

 over twenty-five feet tall. The dwarf white pine, P. Strobus 

 var. nana, forms a low round bush which in ten years does not 

 exceed three feet in height. This is a most important variety 

 in a situation in which a low conifer is required. 



The Swiss stone pine, Pinus Cembra, from central Europe, 

 is of remarkable beauty and quite hardy, as the foliage is not 

 browned by the coldest winters. In its juvenile- state it forms 

 a dense pyramid and is of very slow growth. This pine is well 

 adapted to situations in which space is much restricted. It 

 requires moist good soil. 



The limber pine, Pinus flexilis, from the mountains of 

 California and New Mexico, has usually horizontal and pendu- 

 lous branches, forming a very beautiful outline. Its leaves are 

 short and rigid and look quite different from other white pines. 

 It is quite hardy, of slow growth, and seems to thrive best at 

 the base of a slope where moisture is abundant, but well drained. 



The Korean white pine, Pinus horaiensis, is not a common 

 conifer in American parks or gardens, although it was intro- 

 duced many years ago. The branches spread horizontally, 

 but are somewhat divergent and are inclined in some individuals 

 to be rather thin. It is very hardy and of slow growth, and is well 

 adapted to restricted situations. Occasional removal of the cen- 

 tral buds in spring to produce a dense lateral growth is beneficial. 



The Japanese white pine, Pinus parviflora, has a very 

 characteristic aspect. The short leaves give a tufted, crowded
