Cult. The green-house species will thrive well in any kind 

 of light soil, and are readily increased by cuttings planted under 

 a hand-glass, or by seeds. The hardy perennial kinds by divid- 

 ing the plants at the root, or by seeds ; they will thrive in any 

 kind of soil. The hardy annual sorts only require to be sown in 

 the open ground. None of the species are worth cultivating for 

 ornament.
