Cult. The seeds of Chamlra should be sown in a pot filled 

 with a mixture of peat and sand, in the month of March, then 

 placed in a hot-bed, and when the plants are grown to a suffi- 

 cient size, which will be about the end of April, they may be 

 planted out into the open border, in a dry, warm situation, where 

 they will flower, and ripen their seed.
