Cult. The seeds of the annual species of this genus should 

 be sown in pots, filled with a mixture of loam and sand, which 

 should be placed in a hot-bed, and kept rather moist; and 

 when the plants have attained 2 or 3 inches in height, they 

 should be potted off into separate pots, and again placed into 

 the hot-bed, where they may remain until they have ripened 

 their seed, or be removed to the stove when in flower. The 

 shrubby kind thrive well in the same kind of soil, and young 

 cuttings of them root readily if planted in a pot of sand, with a 

 hand-glass placed over them, in heat.
