Cult. The species are all beautiful tender annuals. The 

 seeds of them should be reared on a hot-bed in early spring, and 

 about the middle or end of May some of the young plants may 

 be set out in the open border, in a warm, sheltered situation ; and 

 others may be grown in pots, and placed in the green-house.
