which may he sown in the common bor- 

 der, at the end of March ; the biennial* 

 may he sown in April or May, many of 

 them will bloom the same year ; by cut- 

 tings a perennial habit will be given to 

 many of them. Perennials, chiefly by 

 division of the plant and roots. Those 

 from the West Indies, New Holland, and 

 the South of Europe, require the protec- 

 tion of a greenhouse, or cold pit, in win-

 window plant C. pyramidalis makes a 

 poor show in the open air in most places. 

 Common soil for the most of them ; a 

 little peat and dung for those in pots.
