necessary that they should be partially covered in the win- 

 ter, to guard them against being injured in that manner. 



In planting hardy herbaceous plants, the principal object to 

 be borne in mind, is their height, color, and time of flowering, 

 in order that they may be so distributed in the beds as to form 

 a pleasing variety, which may be effected by referring to the 

 Descriptive List, subjoined hereto. Care should also be taken 

 that the plants are so chosen as to have a succession of flow- 

 ers during the season. This may be greatly facilitated by 

 cutting down a part of the young shoots of Delphiniums, 

 early flowering, Phlox, &c. to the ground, about the time 

 they are beginning to show their buds ; by this method, a 

 succession of the same kind of flowers may be kept up dur- 

 ing the season ; those which are cut, being deterred from 

 flowering, make a second growth, and come into flower after 

 those of their natural growth have exhausted themselves.
