Cult. All the species are showy border annuals, and are 

 therefore worth cultivating in every garden. The seeds only 

 require to be sown in the open ground, where the plants are 

 intended to remain. By sowing the seeds in the autumn, the 

 plants will blossom early in summer, and by successive sowings 

 in spring, at intervals of a fortnight or three weeks, a succession 

 of blossoming plants may be kept up. 



XVII. TRACHE'LIUM (from rpax>?Xoe, trachelos, the neck; 

 from its supposed efficacy in diseases of the trachea: hence 

 also it is called Throat-nort in England, Halskraut in Ger- 

 many, and Hermorilla, in Spain, &c.). Lin. gen. 293. Adans.

Cult. The species are very showy when in blossom. They 

 grow best in a light soil, against a south wall, or in front of a 

 hot-house ; and they may either be increased by seed or by 

 cuttings, planted under a hand-glass in spring.
