Cult. Most of the kinds of Tobacco are showy when in 

 blossom, and some of them answer well for decorating flower- 

 borders, particularly the white flowered species. The seeds 

 of all require to be reared on a hot-bed in spring, and 

 when the plants are grown with 2 or 3 leaves, they should 



be planted separately into small pots, and placed again in the 

 frame ; and about the end of May those which are intended for 

 the flower border should be planted out in conspicuous situa- 

 tions, and those intended for leaves in rows 3 feet distant, with 

 the balls entire.
