Cult. All the species are of easy culture, and will grow well 

 in any rich light soil. The shrubby kinds are readily increased 

 by cuttings : the perennial herbaceous species by division or by 

 cuttings ; and in summer they will all thrive in the open border ; 

 but in winter they require protection. The seeds of annual kinds 

 only require to be sown in open borders, like those of other 

 hardy annuals.
