SORTS OF PLANTS 



no arbitrary distinction; a small tree is called a tree- 

 like shrub, while a shrub attaining to 30 feet in height 

 is referred to under the same term. The line between 

 the two cannot be sharply denned. 



CLIMBERS are plants of weak stems, sometimes 

 tall and sometimes low growing, which cannot lift 

 themselves without the aid of some support. They 

 may be in any one of the classes mentioned above and 

 they may have woody or juicy stems. Those which 

 twine around their support are, strictly speaking, 

 vines; climbers raise themselves by means of trendrils, 

 aerial rootlets or some special device provided for the 

 purpose. Thus all vines are climbers, but all climb- 

 ers are not vines. Nurserymen commonly mean tall 

 growing plants when they use the term climber; lower 

 growing kinds they define as trailers. 



A difference of a single degree of latitude has a 

 marked effect on many plants, though it is not distance 

 north or south alone that tells. Some regions, for 

 instance, from their topographical peculiarities, may be 

 particularly adapted to the growth of certain things 

 which ordinarily would not be hardy in that latitude; 

 while possibly other localities further south are unfavor- 

 able by reason of their configuration to the cultivation 

 of even lustier species. Altitude enters into the matter 

 to a certain degree, likewise the texture of the soil, the 

 proximity of large bodies of water and the direction of 

 the prevailing winter winds. 



The knowledge that all perennials are not as easily 

 raised from seed as most annuals, and that the latter
