necessary at times, but never heavy waterings for the 

 seedlings. 



The Pyrus Japonica, 



The Perennial Asters, 



The Gentiana, 



The Daisy, 



The Pyrethrums, 



The Lychnis, 



The Arabis, 



The Commelyna, 



The Chelone, and all this class of perennial plants, 

 may be freely propagated by dividing the roots in the 

 spring, as soon as they begin to grow. 



The Potentillas, 



The Catananche, 



The Rochet, 



The Agrostemma, 



The Perennial Lupine, 



The Geum, 



The Linarias, 



The Perennial Poppy, and all this, class, are best 

 raised from seed ; some, however, may be propagated 

 by cuttings, as the double Rocket and the Linaria. 

 All those perennials that throw up numerous stems 

 from the root may be easily multiplied by division — 

 for example, the Monk's Hood, the Aster (or Michael- 

 mas Daisy), the Lychnis, &c. But such as only possess 

 one crown, or rather one underground stem, as in the 

 case of the Perennial Poppy, must, as a rule, be multi- 

 plied by seed. 



The Class of Annuals that must be Raised on 

 Heat first, and Transplanted to where they 

 are to Flower. 



The Aster, many varieties. 



The Braclaycome [Asteracece), two varieties. 



The Browallia {Scrophidariacea). 



The Celosia (Amarantacece). 



The Fenzlia {Polemoniacece).
